These chips are a single +chip PnP sound solution which is mostly hardware compatible with the +Sound Blaster 16 card, with most differences occurring in the use of +the mixer registers. For this reason the ALS code is integrated +as part of the Sound Blaster 16 driver (adding only 800 bytes to the +SB16 driver). + +To use an ALS sound card under Linux, enable the following options as +modules in the sound configuration section of the kernel config: + - 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support + - FM synthesizer (YM3812/OPL-3) support + - standalone MPU401 support may be required for some cards; for the + ALS-007, when using isapnptools, it is required +Since the ALS-007/100/200 are PnP cards, ISAPnP support should probably be +compiled in. If kernel level PnP support is not included, isapnptools will +be required to configure the card before the sound modules are loaded. + +When using kernel level ISAPnP, the kernel should correctly identify and +configure all resources required by the card when the "sb" module is +inserted. Note that the ALS-007 does not have a 16 bit DMA channel and that +the MPU401 interface on this card uses a different interrupt to the audio +section. This should all be correctly configured by the kernel; if problems +with the MPU401 interface surface, try using the standalone MPU401 module, +passing "0" as the "sb" module's "mpu_io" module parameter to prevent the +soundblaster driver attempting to register the MPU401 itself. The onboard +synth device can be accessed using the "opl3" module. + +If isapnptools is used to wake up the sound card (as in 2.2.x), the settings +of the card's resources should be passed to the kernel modules ("sb", "opl3" +and "mpu401") using the module parameters. When configuring an ALS-007, be +sure to specify different IRQs for the audio and MPU401 sections - this card +requires they be different. For "sb", "io", "irq" and "dma" should be set +to the same values used to configure the audio section of the card with +isapnp. "dma16" should be explicitly set to "-1" for an ALS-007 since this +card does not have a 16 bit dma channel; if not specified the kernel will +default to using channel 5 anyway which will cause audio not to work. +"mpu_io" should be set to 0. The "io" parameter of the "opl3" module should +also agree with the setting used by isapnp. To get the MPU401 interface +working on an ALS-007 card, the "mpu401" module will be required since this +card uses separate IRQs for the audio and MPU401 sections and there is no +parameter available to pass a different IRQ to the "sb" driver (whose +inbuilt MPU401 driver would otherwise be fine). Insert the mpu401 module +passing appropriate values using the "io" and "irq" parameters. + +The resulting sound driver will provide the following capabilities: + - 8 and 16 bit audio playback + - 8 and 16 bit audio recording + - Software selection of record source (line in, CD, FM, mic, master) + - Record and playback of midi data via the external MPU-401 + - Playback of midi data using inbuilt FM synthesizer + - Control of the ALS-007 mixer via any OSS-compatible mixer programs. + Controls available are Master (L&R), Line in (L&R), CD (L&R), + DSP/PCM/audio out (L&R), FM (L&R) and Mic in (mono). + +Jonathan Woithe +jwoithe@physics.adelaide.edu.au +30 March 1998 + +Modified 2000-02-26 by Dave Forrest, drf5n@virginia.edu to add ALS100/ALS200 +Modified 2000-04-10 by Paul Laufer, pelaufer@csupomona.edu to add ISAPnP info. +Modified 2000-11-19 by Jonathan Woithe, jwoithe@physics.adelaide.edu.au + - updated information for kernel 2.4.x. diff --git a/Documentation/sound/oss/AWE32 b/Documentation/sound/oss/AWE32 new file mode 100644 index 0000000..cb179bf --- /dev/null +++ b/Documentation/sound/oss/AWE32 @@ -0,0 +1,76 @@ + Installing and using Creative AWE midi sound under Linux. + +This documentation is devoted to the Creative Sound Blaster AWE32, AWE64 and +SB32. + +1) Make sure you have an ORIGINAL Creative SB32, AWE32 or AWE64 card.

From +Alan's comments in linux/drivers/sound/README.FIRST: + + The modular sound driver patches were funded by Red Hat Software + (www.redhat.com). The sound driver here is thus a modified version of + Hannu's code. Please bear that in mind when considering the appropriate + forums for bug reporting. + +The modular sound drivers may be loaded via insmod or modprobe. +To support all the various sound modules, there are two general +support modules that must be loaded first: + + soundcore.o: Top level handler for the sound system, provides + a set of functions for registration of devices + by type. + + sound.o: Common sound functions required by all modules. + +For the specific sound modules (e.g., sb.o for the Soundblaster), +read the documentation on that module to determine what options +are available, for example IRQ, address, DMA. + +Warning, the options for different cards sometime use different names +for the same or a similar feature (dma1= versus dma16=).

There is a new OpenSource sound driver called ALSA which is + currently under development: http://www.alsa-project.org/ + The ALSA drivers support some newer hardware that may not + be supported by this sound driver and also provide some + additional features. + +2. The commercial OSS driver may be obtained from the site: + http://www/opensound.com. This may be used for cards that + are unsupported by the kernel driver, or may be used + by other operating systems. + +3. The enlightenment sound daemon may be used for playing + multiple sounds at the same time via a single card, eliminating + some of the requirements for multiple sound card systems. For + more information, see: http://www.tux.org/~ricdude/EsounD.html + The "esd" program may be used with the real-player and mpeg + players like mpg123 and x11amp. The newer real-player + and some games even include built-in support for ESD! + + +Building the Modules: +===================== + +This document does not provide full details on building the +kernel, etc. The notes below apply only to making the kernel +sound modules. If this conflicts with the kernel's README, +the README takes precedence. + +1. To make the kernel sound modules, cd to your /usr/src/linux + directory (typically) and type make config, make menuconfig, + or make xconfig (to start the command line, dialog, or x-based + configuration tool). + +2. Select the Sound option and a dialog will be displayed. + +3. Select M (module) for "Sound card support". + +4. Select your sound driver(s) as a module. For ProAudio, Sound + Blaster, etc., select M (module) for OSS sound modules. + [thanks to Marvin Stodolsky <stodolsk@erols.com>]A + +5. Make the kernel (e.g., make bzImage), and install the kernel. + +6. Make the modules and install them (make modules; make modules_install). + +Note, for 2.5.x kernels, make sure you have the newer module-init-tools +installed or modules will not be loaded properly. 2.5.x requires an +updated module-init-tools. + + +Plug and Play (PnP: +=================== + +If the sound card is an ISA PnP card, isapnp may be used +to configure the card. See the file isapnp.txt in the +directory one level up (e.g., /usr/src/linux/Documentation). + +Also the 2.4.x kernels provide PnP capabilities, see the +file NEWS in this directory. + +PCI sound cards are highly recommended, as they are far +easier to configure and from what I have read, they use +less resources and are more CPU efficient. + + +INSMOD: +======= + +If loading via insmod, the common modules must be loaded in the +order below BEFORE loading the other sound modules. The card-specific +modules may then be loaded (most require parameters). For example, +I use the following via a shell script to load my SoundBlaster: + +SB_BASE=0x240 +SB_IRQ=9 +SB_DMA=3 +SB_DMA2=5 +SB_MPU=0x300 +# +echo Starting sound +/sbin/insmod soundcore +/sbin/insmod sound +# +echo Starting sound blaster.... +/sbin/insmod uart401 +/sbin/insmod sb io=$SB_BASE irq=$SB_IRQ dma=$SB_DMA dma16=$SB_DMA2 mpu_io=$SB_MP + +When using sound as a module, I typically put these commands +in a file such as /root/soundon.sh. + + +MODPROBE: +========= + +If loading via modprobe, these common files are automatically loaded +when requested by modprobe. For example, my /etc/modprobe.conf contains: + +alias sound sb +options sb io=0x240 irq=9 dma=3 dma16=5 mpu_io=0x300 + +All you need to do to load the module is: + + /sbin/modprobe sb + + +Sound Status: +============= + +The status of sound may be read/checked by: + cat (anyfile).au >/dev/audio + +[WWH: This may not work properly for SoundBlaster PCI 128 cards +such as the es1370/1 (see the es1370/1 files in this directory) +as they do not automatically support uLaw on /dev/audio.] + +The status of the modules and which modules depend on +which other modules may be checked by: + /sbin/lsmod + +/sbin/lsmod should show something like the following: + sb 26280 0 + uart401 5640 0 [sb] + sound 57112 0 [sb uart401] + soundcore 1968 8 [sb sound] + + +Removing Sound: +=============== + +Sound may be removed by using /sbin/rmmod in the reverse order +in which you load the modules. Note, if a program has a sound device +open (e.g., xmixer), that module (and the modules on which it +depends) may not be unloaded. + +For example, I use the following to remove my Soundblaster (rmmod +in the reverse order in which I loaded the modules): + +/sbin/rmmod sb +/sbin/rmmod uart401 +/sbin/rmmod sound +/sbin/rmmod soundcore + +When using sound as a module, I typically put these commands +in a script such as /root/soundoff.sh. + + +Removing Sound for use with OSS: +================================ + +If you get really stuck or have a card that the kernel modules +will not support, you can get a commercial sound driver from +http://www.opensound.com. Before loading the commercial sound +driver, you should do the following: + +1. remove sound modules (detailed above) +2. remove the sound modules from /etc/modprobe.conf +3. move the sound modules from /lib/modules/<kernel>/misc + (for example, I make a /lib/modules/<kernel>/misc/tmp + directory and copy the sound module files to that + directory). + + +Multiple Sound Cards: +===================== + +The sound drivers will support multiple sound cards and there +are some great applications like multitrack that support them. +Typically, you need two sound cards of different types. Note, this +uses more precious interrupts and DMA channels and sometimes +can be a configuration nightmare. I have heard reports of 3-4 +sound cards (typically I only use 2). You can sometimes use +multiple PCI sound cards of the same type. + +On my machine I have two sound cards (cs4232 and Soundblaster Vibra +16). By loading sound as modules, I can control which is the first +sound device (/dev/dsp, /dev/audio, /dev/mixer) and which is +the second. Normally, the cs4232 (Dell sound on the motherboard) +would be the first sound device, but I prefer the Soundblaster. +All you have to do is to load the one you want as /dev/dsp +first (in my case "sb") and then load the other one +(in my case "cs4232"). + +If you have two cards of the same type that are jumpered +cards or different PnP revisions, you may load the same +module twice. For example, I have a SoundBlaster vibra 16 +and an older SoundBlaster 16 (jumpers). To load the module +twice, you need to do the following: + +1. Copy the sound modules to a new name. For example + sb.o could be copied (or symlinked) to sb1.o for the + second SoundBlaster. + +2. Make a second entry in /etc/modprobe.conf, for example, + sound1 or sb1. This second entry should refer to the + new module names for example sb1, and should include + the I/O, etc. for the second sound card. + +3. Update your soundon.sh script, etc. + +Warning: I have never been able to get two PnP sound cards of the +same type to load at the same time. I have tried this several times +with the Soundblaster Vibra 16 cards. OSS has indicated that this +is a PnP problem.... If anyone has any luck doing this, please +send me an E-MAIL. PCI sound cards should not have this problem.a +Since this was originally release, I have received a couple of +mails from people who have accomplished this! + +NOTE: In Linux 2.4 the Sound Blaster driver (and only this one yet) +supports multiple cards with one module by default. +Read the file 'Soundblaster' in this directory for details. + + +Sound Problems: +=============== + +First RTFM (including the troubleshooting section +in the Sound-HOWTO). + +1) If you are having problems loading the modules (for + example, if you get device conflict errors) try the + following: + + A) If you have Win95 or NT on the same computer, + write down what addresses, IRQ, and DMA channels + those were using for the same hardware. You probably + can use these addresses, IRQs, and DMA channels. + You should really do this BEFORE attempting to get + sound working! + + B) Check (cat) /proc/interrupts, /proc/ioports, + and /proc/dma. Are you trying to use an address, + IRQ or DMA port that another device is using? + + C) Check (cat) /proc/isapnp + + D) Inspect your /var/log/messages file. Often that will + indicate what IRQ or IO port could not be obtained. + + E) Try another port or IRQ. Note this may involve + using the PnP tools to move the sound card to + another location. Sometimes this is the only way + and it is more or less trial and error. + +2) If you get motor-boating (the same sound or part of a + sound clip repeated), you probably have either an IRQ + or DMA conflict. Move the card to another IRQ or DMA + port. This has happened to me when playing long files + when I had an IRQ conflict. + +3. If you get dropouts or pauses when playing high sample + rate files such as using mpg123 or x11amp/xmms, you may + have too slow of a CPU and may have to use the options to + play the files at 1/2 speed. For example, you may use + the -2 or -4 option on mpg123. You may also get this + when trying to play mpeg files stored on a CD-ROM + (my Toshiba T8000 PII/366 sometimes has this problem). + +4. If you get "cannot access device" errors, your /dev/dsp + files, etc. may be set to owner root, mode 600. You + may have to use the command: + chmod 666 /dev/dsp /dev/mixer /dev/audio + +5. If you get "device busy" errors, another program has the + sound device open. For example, if using the Enlightenment + sound daemon "esd", the "esd" program has the sound device. + If using "esd", please RTFM the docs on ESD. For example, + esddsp <program> may be used to play files via a non-esd + aware program. + +6) Ask for help on the sound list or send E-MAIL to the + sound driver author/maintainer. + +7) Turn on debug in drivers/sound/sound_config.h (DEB, DDB, MDB). + +8) If the system reports insufficient DMA memory then you may want to + load sound with the "dmabufs=1" option. Or in /etc/conf.modules add + + preinstall sound dmabufs=1 + + This makes the sound system allocate its buffers and hang onto them. + + You may also set persistent DMA when building a 2.4.x kernel. + + +Configuring Sound: +================== + +There are several ways of configuring your sound: + +1) On the kernel command line (when using the sound driver(s) + compiled in the kernel). Check the driver source and + documentation for details. + +2) On the command line when using insmod or in a bash script + using command line calls to load sound. + +3) In /etc/modprobe.conf when using modprobe. + +4) Via Red Hat's GPL'd /usr/sbin/sndconfig program (text based). + +5) Via the OSS soundconf program (with the commercial version + of the OSS driver. + +6) By just loading the module and let isapnp do everything relevant + for you. This works only with a few drivers yet and - of course - + only with isapnp hardware. + +And I am sure, several other ways. + +Anyone want to write a linuxconf module for configuring sound? + + +Module Loading: +=============== + +When a sound card is first referenced and sound is modular, the sound system +will ask for the sound devices to be loaded. Initially it requests that +the driver for the sound system is loaded. It then will ask for +sound-slot-0, where 0 is the first sound card. (sound-slot-1 the second and +so on). Thus you can do + +alias sound-slot-0 sb + +To load a soundblaster at this point.

The first +is the Maestro 1. It was originally produced by Platform Tech as the +'AGOGO'. It can be recognized by Platform Tech's PCI ID 0x1285 with +0x0100 as the device ID. It was put on some sound boards and a few laptops. +ESS bought the design and cleaned it up as the Maestro 2. This starts +their marking with the ESS vendor ID 0x125D and the 'year' device IDs. +The Maestro 2 claims 0x1968 while the Maestro 2e has 0x1978. + +The various families of Maestro are mostly identical as far as this +driver is concerned. It doesn't touch the DSP parts that differ (though +it could for FM synthesis). + +Driver OSS Behavior +-------------------- + +This OSS driver exports /dev/mixer and /dev/dsp to applications, which +mostly adhere to the OSS spec. This driver doesn't register itself +with /dev/sndstat, so don't expect information to appear there. + +The /dev/dsp device exported behaves almost as expected. Playback is +supported in all the various lovely formats. 8/16bit stereo/mono from +8khz to 48khz, and mmap()ing for playback behaves. Capture/recording +is limited due to oddities with the Maestro hardware. One can only +record in 16bit stereo. For recording the maestro uses non interleaved +stereo buffers so that mmap()ing the incoming data does not result in +a ring buffer of LRLR data. mmap()ing of the read buffers is therefore +disallowed until this can be cleaned up. + +/dev/mixer is an interface to the AC'97 codec on the Maestro. It is +worth noting that there are a variety of AC'97s that can be wired to +the Maestro. Which is used is entirely up to the hardware implementor. +This should only be visible to the user by the presence, or lack, of +'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them. + +The driver doesn't support MIDI or FM playback at the moment. Typically +the Maestro is wired to an MPU MIDI chip, but some hardware implementations +don't. We need to assemble a white list of hardware implementations that +have MIDI wired properly before we can claim to support it safely. + +Compiling and Installing +------------------------ + +With the drivers inclusion into the kernel, compiling and installing +is the same as most OSS/Lite modular sound drivers. Compilation +of the driver is enabled through the CONFIG_SOUND_MAESTRO variable +in the config system. + +It may be modular or statically linked. If it is modular it should be +installed with the rest of the modules for the kernel on the system. +Typically this will be in /lib/modules/ somewhere. 'alias sound maestro' +should also be added to your module configs (typically /etc/conf.modules) +if you're using modular OSS/Lite sound and want to default to using a +maestro chip. + +As this is a PCI device, the module does not need to be informed of +any IO or IRQ resources it should use, it devines these from the +system. Sometimes, on sucky PCs, the BIOS fails to allocated resources +for the maestro. This will result in a message like: + maestro: PCI subsystem reports IRQ 0, this might not be correct. +from the kernel. Should this happen the sound chip most likely will +not operate correctly. To solve this one has to dig through their BIOS +(typically entered by hitting a hot key at boot time) and figure out +what magic needs to happen so that the BIOS will reward the maestro with +an IRQ. This operation is incredibly system specific, so you're on your +own. Sometimes the magic lies in 'PNP Capable Operating System' settings. + +There are very few options to the driver. One is 'debug' which will +tell the driver to print minimal debugging information as it runs. This +can be collected with 'dmesg' or through the klogd daemon. + +The other, more interesting option, is 'dsps_order'. Typically at +install time the driver will only register one available /dev/dsp device +for its use. The 'dsps_order' module parameter allows for more devices +to be allocated, as a power of two. Up to 4 devices can be registered +( dsps_order=2 ). These devices act as fully distinct units and use +separate channels in the maestro. + +Power Management +---------------- + +As of version 0.14, this driver has a minimal understanding of PCI +Power Management. If it finds a valid power management capability +on the PCI device it will attempt to use the power management +functions of the maestro. It will only do this on Maestro 2Es and +only on machines that are known to function well. You can +force the use of power management by setting the 'use_pm' module +option to 1, or can disable it entirely by setting it to 0. + +When using power management, the driver does a few things +differently. It will keep the chip in a lower power mode +when the module is inserted but /dev/dsp is not open. This +allows the mixer to function but turns off the clocks +on other parts of the chip. When /dev/dsp is opened the chip +is brought into full power mode, and brought back down +when it is closed. It also powers down the chip entirely +when the module is removed or the machine is shutdown. This +can have nonobvious consequences. CD audio may not work +after a power managing driver is removed. Also, software that +doesn't understand power management may not be able to talk +to the powered down chip until the machine goes through a hard +reboot to bring it back. + +.. more details .. +------------------ + +drivers/sound/maestro.c contains comments that hopefully explain +the maestro implementation. diff --git a/Documentation/sound/oss/Maestro3 b/Documentation/sound/oss/Maestro3 new file mode 100644 index 0000000..a113718 --- /dev/null +++ b/Documentation/sound/oss/Maestro3 @@ -0,0 +1,92 @@ + An OSS/Lite Driver for the ESS Maestro3 family of sound chips + + Zach Brown, January 2001 + +Driver Status and Availability +------------------------------ + +The most recent version of this driver will hopefully always be available at + http://www.zabbo.net/maestro3/ + +I will try and maintain the most recent stable version of the driver +in both the stable and development kernel lines. + +Historically I've sucked pretty hard at actually doing that, however. + +ESS Maestro3 Chip Family +----------------------- + +The 'Maestro3' is much like the Maestro2 chip. The noted improvement +is the removal of the silicon in the '2' that did PCM mixing. All that +work is now done through a custom DSP called the ASSP, the Asynchronus +Specific Signal Processor. + +The 'Allegro' is a baby version of the Maestro3. I'm not entirely clear +on the extent of the differences, but the driver supports them both :) + +The 'Allegro' shows up as PCI ID 0x1988 and the Maestro3 as 0x1998, +both under ESS's vendor ID of 0x125D. The Maestro3 can also show up as +0x199a when hardware strapping is used. + +The chip can also act as a multi function device. The modem IDs follow +the audio multimedia device IDs. (so the modem part of an Allegro shows +up as 0x1989) + +Driver OSS Behavior +-------------------- + +This OSS driver exports /dev/mixer and /dev/dsp to applications, which +mostly adhere to the OSS spec. This driver doesn't register itself +with /dev/sndstat, so don't expect information to appear there. + +The /dev/dsp device exported behaves as expected. Playback is +supported in all the various lovely formats. 8/16bit stereo/mono from +8khz to 48khz, with both read()/write(), and mmap(). + +/dev/mixer is an interface to the AC'97 codec on the Maestro3. It is +worth noting that there are a variety of AC'97s that can be wired to +the Maestro3. Which is used is entirely up to the hardware implementor. +This should only be visible to the user by the presence, or lack, of +'Bass' and 'Treble' sliders in the mixer. Not all AC'97s have them. +The Allegro has an onchip AC'97. + +The driver doesn't support MIDI or FM playback at the moment. + +Compiling and Installing +------------------------ + +With the drivers inclusion into the kernel, compiling and installing +is the same as most OSS/Lite modular sound drivers. Compilation +of the driver is enabled through the CONFIG_SOUND_MAESTRO3 variable +in the config system. + +It may be modular or statically linked. If it is modular it should be +installed with the rest of the modules for the kernel on the system. +Typically this will be in /lib/modules/ somewhere. 'alias sound-slot-0 +maestro3' should also be added to your module configs (typically +/etc/modprobe.conf) if you're using modular OSS/Lite sound and want to +default to using a maestro3 chip. + +There are very few options to the driver. One is 'debug' which will +tell the driver to print minimal debugging information as it runs. This +can be collected with 'dmesg' or through the klogd daemon. + +One is 'external_amp', which tells the driver to attempt to enable +an external amplifier. This defaults to '1', you can tell the driver +not to bother enabling such an amplifier by setting it to '0'. + +And the last is 'gpio_pin', which tells the driver which GPIO pin number +the external amp uses (0-15), The Allegro uses 8 by default, all others 1. +If everything loads correctly and seems to be working but you get no sound, +try tweaking this value. + +Systems known to need a different value + Panasonic ToughBook CF-72: gpio_pin=13 + +Power Management +---------------- + +This driver has a minimal understanding of PCI Power Management. It will +try and power down the chip when the system is suspended, and power +it up with it is resumed. It will also try and power down the chip +when the machine is shut down. diff --git a/Documentation/sound/oss/MultiSound b/Documentation/sound/oss/MultiSound new file mode 100644 index 0000000..e4a18bb --- /dev/null +++ b/Documentation/sound/oss/MultiSound @@ -0,0 +1,1137 @@ +#! /bin/sh +# +# Turtle Beach MultiSound Driver Notes +# -- Andrew Veliath <andrewtv@usa.net> +# +# Last update: September 10, 1998 +# Corresponding msnd driver: 0.8.3 +# +# ** This file is a README (top part) and shell archive (bottom part). +# The corresponding archived utility sources can be unpacked by +# running `sh MultiSound' (the utilities are only needed for the +# Pinnacle and Fiji cards). ** +# +# +# -=-=- Getting Firmware -=-=- +# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +# +# See the section `Obtaining and Creating Firmware Files' in this +# document for instructions on obtaining the necessary firmware +# files. +# +# +# Supported Features +# ~~~~~~~~~~~~~~~~~~ +# +# Currently, full-duplex digital audio (/dev/dsp only, /dev/audio is +# not currently available) and mixer functionality (/dev/mixer) are +# supported (memory mapped digital audio is not yet supported). +# Digital transfers and monitoring can be done as well if you have +# the digital daughterboard (see the section on using the S/PDIF port +# for more information). +# +# Support for the Turtle Beach MultiSound Hurricane architecture is +# composed of the following modules (these can also operate compiled +# into the kernel): +# +# msnd - MultiSound base (requires soundcore) +# +# msnd_classic - Base audio/mixer support for Classic, Monetery and +# Tahiti cards +# +# msnd_pinnacle - Base audio/mixer support for Pinnacle and Fiji cards +# +# +# Important Notes - Read Before Using +# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +# +# The firmware files are not included (may change in future).

You must +# know the io port, then the driver will select the irq and memory resources +# on the card. It is up to you to know if these are free locations or now, +# a conflict can lock the machine up. +# +# * Pinnacle/Fiji +# +# The Pinnacle and Fiji cards have an extra config port, either +# 0x250, 0x260 or 0x270. This port can be disabled to have the card +# configured strictly through PnP, however you lose the ability to +# access the IDE controller and joystick devices on this card when +# using PnP. The included pinnaclecfg program in this shell archive +# can be used to configure the card in non-PnP mode, and in PnP mode +# you can use isapnptools. These are described briefly here. +# +# pinnaclecfg is not required; you can use the msnd_pinnacle module +# to fully configure the card as well. However, pinnaclecfg can be +# used to change the resource values of a particular device after the +# msnd_pinnacle module has been loaded. If you are compiling the +# driver into the kernel, you must set these values during compile +# time, however other peripheral resource values can be changed with +# the pinnaclecfg program after the kernel is loaded. +# +# +# *** PnP mode +# +# Use pnpdump to obtain a sample configuration if you can; I was able +# to obtain one with the command `pnpdump 1 0x203' -- this may vary +# for you (running pnpdump by itself did not work for me). Then, +# edit this file and use isapnp to uncomment and set the card values. +# Use these values when inserting the msnd_pinnacle module. Using +# this method, you can set the resources for the DSP and the Kurzweil +# synth (Pinnacle). Since Linux does not directly support PnP +# devices, you may have difficulty when using the card in PnP mode +# when it the driver is compiled into the kernel. Using non-PnP mode +# is preferable in this case. +# +# Here is an example mypinnacle.conf for isapnp that sets the card to +# io base 0x210, irq 5 and mem 0xd8000, and also sets the Kurzweil +# synth to 0x330 and irq 9 (may need editing for your system): +# +# (READPORT 0x0203) +# (CSN 2) +# (IDENTIFY *) +# +# # DSP +# (CONFIGURE BVJ0440/-1 (LD 0 +# (INT 0 (IRQ 5 (MODE +E))) (IO 0 (BASE 0x0210)) (MEM 0 (BASE 0x0d8000)) +# (ACT Y))) +# +# # Kurzweil Synth (Pinnacle Only) +# (CONFIGURE BVJ0440/-1 (LD 1 +# (IO 0 (BASE 0x0330)) (INT 0 (IRQ 9 (MODE +E))) +# (ACT Y))) +# +# (WAITFORKEY) +# +# +# *** Non-PnP mode +# +# The second way is by running the card in non-PnP mode. This +# actually has some advantages in that you can access some other +# devices on the card, such as the joystick and IDE controller. To +# configure the card, unpack this shell archive and build the +# pinnaclecfg program. Using this program, you can assign the +# resource values to the card's devices, or disable the devices.

(Woohoo!) It has been +successfully tested against the following laptop models: + + Sony Z505S/Z505SX/Z505DX/Z505RX + Sony F150, F160, F180, F250, F270, F280, PCG-F26 + Dell Latitude CPi, CPt (various submodels) + +There are a few caveats, which is why you should read the entirety of +this document first. + +This driver was developed without any support or assistance from +NeoMagic. There is no warranty, expressed, implied, or otherwise. It +is free software in the public domain; feel free to use it, sell it, +give it to your best friends, even claim that you wrote it (but why?!) +but don't go whining to me, NeoMagic, Sony, Dell, or anyone else +when it blows up your computer. + +Version 1.1 contains a change to try and detect non-AC97 versions of +the hardware, and not install itself appropriately. It should also +reinitialize the hardware on an APM resume event, assuming that APM +was configured into your kernel. + +============ +Installation +============ + +Enable the sound drivers, the OSS sound drivers, and then the NM256 +driver. The NM256 driver *must* be configured as a module (it won't +give you any other choice). + +Next, do the usual "make modules" and "make modules_install". +Finally, insmod the soundcore, sound and nm256 modules. + +When the nm256 driver module is loaded, you should see a couple of +confirmation messages in the kernel logfile indicating that it found +the device (the device does *not* use any I/O ports or DMA channels). +Now try playing a wav file, futz with the CD-ROM if you have one, etc. + +The NM256 is entirely a PCI-based device, and all the necessary +information is automatically obtained from the card. It can only be +configured as a module in a vain attempt to prevent people from +hurting themselves. It works correctly if it shares an IRQ with +another device (it normally shares IRQ 9 with the builtin eepro100 +ethernet on the Sony Z505 laptops). + +It does not run the card in any sort of compatibility mode. It will +not work on laptops that have the SB16-compatible, AD1848-compatible +or CS4232-compatible codec/mixer; you will want to use the appropriate +compatible OSS driver with these chipsets. I cannot provide any +assistance with machines using the SB16, AD1848 or CS4232 compatible +versions. (The driver now attempts to detect the mixer version, and +will refuse to load if it believes the hardware is not +AC97-compatible.) + +The sound support is very basic, but it does include simultaneous +playback and record capability. The mixer support is also quite +simple, although this is in keeping with the rather limited +functionality of the chipset. + +There is no hardware synthesizer available, as the Losedows OPL-3 and +MIDI support is done via hardware emulation. + +Only three recording devices are available on the Sony: the +microphone, the CD-ROM input, and the volume device (which corresponds +to the stereo output). (Other devices may be available on other +models of laptops.) The Z505 series does not have a builtin CD-ROM, +so of course the CD-ROM input doesn't work. It does work on laptops +with a builtin CD-ROM drive. + +The mixer device does not appear to have any tone controls, at least +on the Z505 series. The mixer module checks for tone controls in the +AC97 mixer, and will enable them if they are available. + +============== +Known problems +============== + + * There are known problems with PCMCIA cards and the eepro100 ethernet + driver on the Z505S/Z505SX/Z505DX. Keep reading. + + * There are also potential problems with using a virtual X display, and + also problems loading the module after the X server has been started. + Keep reading. + + * The volume control isn't anywhere near linear. Sorry. This will be + fixed eventually, when I get sufficiently annoyed with it. (I doubt + it will ever be fixed now, since I've never gotten sufficiently + annoyed with it and nobody else seems to care.) + + * There are reports that the CD-ROM volume is very low. Since I do not + have a CD-ROM equipped laptop, I cannot test this (it's kinda hard to + do remotely). + + * Only 8 fixed-rate speeds are supported. This is mainly a chipset + limitation. It may be possible to support other speeds in the future. + + * There is no support for the telephone mixer/codec. There is support + for a phonein/phoneout device in the mixer driver; whether or not + it does anything is anyone's guess. (Reports on this would be + appreciated. You'll have to figure out how to get the phone to + go off-hook before it'll work, tho.) + + * This driver was not written with any cooperation or support from + NeoMagic. If you have any questions about this, see their website + for their official stance on supporting open source drivers. + +============ +Video memory +============ + +The NeoMagic sound engine uses a portion of the display memory to hold +the sound buffer. (Crazy, eh?) The NeoMagic video BIOS sets up a +special pointer at the top of video RAM to indicate where the top of +the audio buffer should be placed. + +At the present time XFree86 is apparently not aware of this. It will +thus write over either the pointer or the sound buffer with abandon. +(Accelerated-X seems to do a better job here.) + +This implies a few things: + + * Sometimes the NM256 driver has to guess at where the buffer + should be placed, especially if the module is loaded after the + X server is started. It's usually correct, but it will consistently + fail on the Sony F250. + + * Virtual screens greater than 1024x768x16 under XFree86 are + problematic on laptops with only 2.5MB of screen RAM. This + includes all of the 256AV-equipped laptops. (Virtual displays + may or may not work on the 256ZX, which has at least 4MB of + video RAM.) + +If you start having problems with random noise being output either +constantly (this is the usual symptom on the F250), or when windows +are moved around (this is the usual symptom when using a virtual +screen), the best fix is to + + * Don't use a virtual frame buffer. + * Make sure you load the NM256 module before the X server is + started. + +On the F250, it is possible to force the driver to load properly even +after the XFree86 server is started by doing: + + insmod nm256 buffertop=0x25a800 + +This forces the audio buffers to the correct offset in screen RAM. + +One user has reported a similar problem on the Sony F270, although +others apparently aren't seeing any problems. His suggested command +is + + insmod nm256 buffertop=0x272800 + +================= +Official WWW site +================= + +The official site for the NM256 driver is: + + http://www.uglx.org/sony.html + +You should always be able to get the latest version of the driver there, +and the driver will be supported for the foreseeable future. + +============== +Z505RX and IDE +============== + +There appears to be a problem with the IDE chipset on the Z505RX; one +of the symptoms is that sound playback periodically hangs (when the +disk is accessed). The user reporting the problem also reported that +enabling all of the IDE chipset workarounds in the kernel solved the +problem, tho obviously only one of them should be needed--if someone +can give me more details I would appreciate it. + +============================== +Z505S/Z505SX on-board Ethernet +============================== + +If you're using the on-board Ethernet Pro/100 ethernet support on the Z505 +series, I strongly encourage you to download the latest eepro100 driver from +Donald Becker's site: + + ftp://cesdis.gsfc.nasa.gov/pub/linux/drivers/test/eepro100.c + +There was a reported problem on the Z505SX that if the ethernet +interface is disabled and reenabled while the sound driver is loaded, +the machine would lock up. I have included a workaround that is +working satisfactorily. However, you may occasionally see a message +about "Releasing interrupts, over 1000 bad interrupts" which indicates +that the workaround is doing its job. + +================================== +PCMCIA and the Z505S/Z505SX/Z505DX +================================== + +There is also a known problem with the Sony Z505S and Z505SX hanging +if a PCMCIA card is inserted while the ethernet driver is loaded, or +in some cases if the laptop is suspended. This is caused by tons of +spurious IRQ 9s, probably generated from the PCMCIA or ACPI bridges. + +There is currently no fix for the problem that works in every case. +The only known workarounds are to disable the ethernet interface +before inserting or removing a PCMCIA card, or with some cards +disabling the PCMCIA card before ejecting it will also help the +problem with the laptop hanging when the card is ejected. + +One user has reported that setting the tcic's cs_irq to some value +other than 9 (like 11) fixed the problem. This doesn't work on my +Z505S, however--changing the value causes the cardmgr to stop seeing +card insertions and removals, cards don't seem to work correctly, and +I still get hangs if a card is inserted when the kernel is booted. + +Using the latest ethernet driver and pcmcia package allows me to +insert an Adaptec 1480A SlimScsi card without the laptop hanging, +although I still have to shut down the card before ejecting or +powering down the laptop. However, similar experiments with a DE-660 +ethernet card still result in hangs when the card is inserted. I am +beginning to think that the interrupts are CardBus-related, since the +Adaptec card is a CardBus card, and the DE-660 is not; however, I +don't have any other CardBus cards to test with. + +====== +Thanks +====== + +First, I want to thank everyone (except NeoMagic of course) for their +generous support and encouragement. I'd like to list everyone's name +here that replied during the development phase, but the list is +amazingly long. + +I will be rather unfair and single out a few people, however: + + Justin Maurer, for being the first random net.person to try it, + and for letting me login to his Z505SX to get it working there + + Edi Weitz for trying out several different versions, and giving + me a lot of useful feedback + + Greg Rumple for letting me login remotely to get the driver + functional on the 256ZX, for his assistance on tracking + down all sorts of random stuff, and for trying out Accel-X + + Zach Brown, for the initial AC97 mixer interface design + + Jeff Garzik, for various helpful suggestions on the AC97 + interface + + "Mr. Bumpy" for feedback on the Z505RX + + Bill Nottingham, for generous assistance in getting the mixer ID + code working + +================= +Previous versions +================= + +Versions prior to 0.3 (aka `noname') had problems with weird artifacts +in the output and failed to set the recording rate properly. These +problems have long since been fixed. + +Versions prior to 0.5 had problems with clicks in the output when +anything other than 16-bit stereo sound was being played, and also had +periodic clicks when recording. + +Version 0.7 first incorporated support for the NM256ZX chipset, which +is found on some Dell Latitude laptops (the CPt, and apparently +some CPi models as well). It also included the generic AC97 +mixer module. + +Version 0.75 renamed all the functions and files with slightly more +generic names. + +Note that previous versions of this document claimed that recording was +8-bit only; it actually has been working for 16-bits all along. diff --git a/Documentation/sound/oss/OPL3 b/Documentation/sound/oss/OPL3 new file mode 100644 index 0000000..2468ff8 --- /dev/null +++ b/Documentation/sound/oss/OPL3 @@ -0,0 +1,6 @@ +A pure OPL3 card is nice and easy to configure.

After an email exhange with +Yamaha, however, it turns out that the 719 is just a re-badged +715, and the chipsets are identical. The chipset detection code +has been updated to reflect this. + +Anyways, all of these chipsets implement the following devices: + +OPL3 FM synthesizer +Soundblaster Pro +Microsoft/Windows Sound System +MPU401 MIDI interface + +Note that this driver uses the MSS device, and to my knowledge these +chipsets enforce an either/or situation with the Soundblaster Pro +device and the MSS device. Since the MSS device has better +capabilities, I have implemented the driver to use it. + + +Mixer Channels +-------------- + +Older versions of this driver (pre-December 2000) had two mixers, +an OPL3-SA2 or SA3 mixer and a MSS mixer. The OPL3-SA[23] mixer +device contained a superset of mixer channels consisting of its own +channels and all of the MSS mixer channels. To simplify the driver +considerably, and to partition functionality better, the OPL3-SA[23] +mixer device now contains has its own specific mixer channels. They +are: + +Volume - Hardware master volume control +Bass - SA3 only, now supports left and right channels +Treble - SA3 only, now supports left and right channels +Microphone - Hardware microphone input volume control +Digital1 - Yamaha 3D enhancement "Wide" mixer + +All other mixer channels (e.g. "PCM", "CD", etc.) now have to be +controlled via the "MS Sound System (CS4231)" mixer. To facilitate +this, the mixer device creation order has been switched so that +the MSS mixer is created first. This allows accessing the majority +of the useful mixer channels even via single mixer-aware tools +such as "aumix". + + +Plug 'n Play +------------ + +In previous kernels (2.2.x), some configuration was required to +get the driver to talk to the card. Being the new millennium and +all, the 2.4.x kernels now support auto-configuration if ISA PnP +support is configured in. Theoretically, the driver even supports +having more than one card in this case. + +With the addition of PnP support to the driver, two new parameters +have been added to control it: + +isapnp - set to 0 to disable ISA PnP card detection + +multiple - set to 0 to disable multiple PnP card detection + + +Optional Parameters +------------------- + +Recent (December 2000) additions to the driver (based on a patch +provided by Peter Englmaier) are two new parameters: + +ymode - Set Yamaha 3D enhancement mode: + 0 = Desktop/Normal 5-12 cm speakers + 1 = Notebook PC (1) 3 cm speakers + 2 = Notebook PC (2) 1.5 cm speakers + 3 = Hi-Fi 16-38 cm speakers + +loopback - Set A/D input source.

Any feedback on its usefulness +would be appreciated. + + +Manual Configuration +-------------------- + +If for some reason you decide not to compile ISA PnP support into +your kernel, or disabled the driver's usage of it by setting the +isapnp parameter as discussed above, then you will need to do some +manual configuration. There are two ways of doing this. The most +common is to use the isapnptools package to initialize the card, and +use the kernel module form of the sound subsystem and sound drivers. +Alternatively, some BIOS's allow manual configuration of installed +PnP devices in a BIOS menu, which should allow using the non-modular +sound drivers, i.e. built into the kernel. + +I personally use isapnp and modules, and do not have access to a PnP +BIOS machine to test. If you have such a beast, configuring the +driver to be built into the kernel should just work (thanks to work +done by David Luyer <luyer@ucs.uwa.edu.au>). You will still need +to specify settings, which can be done by adding: + +opl3sa2=<io>,<irq>,<dma>,<dma2>,<mssio>,<mpuio> + +to the kernel command line. For example: + +opl3sa2=0x370,5,0,1,0x530,0x330 + +If you are instead using the isapnp tools (as most people have been +before Linux 2.4.x), follow the directions in their documentation to +produce a configuration file.

If you get an +error message while trying to insert the opl3sa2 module, then make +sure that the values of the various arguments match what you specified +in your isapnp configuration file, and that there is no conflict with +another device for an I/O port or interrupt. Checking the contents of +/proc/ioports and /proc/interrupts can be useful to see if you're +butting heads with another device. + +If you still cannot get the module to load, look at the contents of +your system log file, usually /var/log/messages. If you see the +message "opl3sa2: Unknown Yamaha audio controller version", then you +have a different chipset version than I've encountered so far. Look +for all messages in the log file that start with "opl3sa2: " and see +if they provide any clues.

There is a built-in alias that translates this +request to loading the main sound module. + +The sound module in its turn will request loading of a sub-driver +for mixer, audio, midi or synthesizer device. The first 3 are +supported by the mad16 driver. The synth device is supported +by the opl3 driver. + +There is currently no way to autoload the sound device driver +if more than one card is installed. + +options sb mad16=1 + +This is left for historical reasons.

The source +for ad1848_mixer_reroute is appended to the end of this readme +file. It is impossible for the sound driver to know the actual +connections to the mixer. The 3 inputs intended for cd, synth +and line-in are mapped to the generic inputs line1, line2 and +line3. This program reroutes these mixer channels to their +right names (note the right mapping depends on the actual sound +card that you use). +The numeric parameters mean: + 14=line1 8=cd - reroute line1 to the CD input. + 15=line2 3=synth - reroute line2 to the synthesizer input. + 16=line3 6=line - reroute line3 to the line input. +For reference on other input names look at the file +/usr/include/linux/soundcard.h. + +Using a joystick +----------------- +You must enable a joystick in the mad16 options. (also +in /etc/isapnp.conf if you use it). +Tested with regular analog joysticks. + +A CDROM drive connected to the sound card +----------------------------------------- +The 82C931 chip has support only for secondary ATAPI cdrom. +(cdtype=8). Loading the mad16 driver resets the C931 chip +and if a cdrom was already mounted it may cause a complete +system hang. Do not use the sound card if you have an alternative. +If you do use the sound card it is important that you load +the mad16 driver (use "modprobe mad16" to prevent auto-unloading) +before the cdrom is accessed the first time. + +Using the sound driver built-in to the kernel may help here, but... +Most new systems have a PnP BIOS and also two IDE controllers. +The IDE controller on the sound card may be needed only on older +systems (which have only one IDE controller) but these systems +also do not have a PnP BIOS - requiring isapnptools and a modularized +driver. + +Known problems +-------------- +1. See the section on "A CDROM drive connected to the sound card". + +2. On my system the codec cannot capture companded sound samples. + (eg., recording from /dev/audio).

These features include the +ability to enable both the builtin CDROM and joystick ports. + +pss_enable_joystick + + This parameter is basically a flag. A 0 will leave the joystick port +disabled, while a non-zero value would enable the joystick port. The default +setting is pss_enable_joystick=0 as this keeps this driver fully compatible +with systems that were using previous versions of this driver. If you wish to +enable the joystick port you will have to add pss_enable_joystick=1 as an +argument to the driver. To actually use the joystick port you will then have +to load the joystick driver itself. Just remember to load the joystick driver +AFTER the pss sound driver. + +pss_cdrom_port + + This parameter takes a port address as its parameter. Any available port +address can be specified to enable the CDROM port, except for 0x0 and -1 as +these values would leave the port disabled. Like the joystick port, the cdrom +port will require that an appropriate CDROM driver be loaded before you can make +use of the newly enabled CDROM port. Like the joystick port option above, +remember to load the CDROM driver AFTER the pss sound driver. While it may +differ on some PSS sound cards, all the PSS sound cards that I have seen have a +builtin Wearnes CDROM port. If this is the case with your PSS sound card you +should load aztcd with the appropriate port option that matches the port you +assigned to the CDROM port when you loaded your pss sound driver. (ex. +modprobe pss pss_cdrom_port=0x340 && modprobe aztcd aztcd=0x340) The default +setting of this parameter leaves the CDROM port disabled to maintain full +compatibility with systems using previous versions of this driver. + + Other options have also been added for the added convenience and utility +of the user. These options are only available if this driver is loaded as a +module. + +pss_no_sound + + This module parameter is a flag that can be used to tell the driver to +just configure non-sound components. 0 configures all components, a non-0 +value will only attept to configure the CDROM and joystick ports. This +parameter can be used by a user who only wished to use the builtin joystick +and/or CDROM port(s) of his PSS sound card. If this driver is loaded with this +parameter and with the parameter below set to true then a user can safely unload +this driver with the following command "rmmod pss && rmmod ad1848 && rmmod +mpu401 && rmmod sound && rmmod soundcore" and retain the full functionality of +his CDROM and/or joystick port(s) while gaining back the memory previously used +by the sound drivers. This default setting of this parameter is 0 to retain +full behavioral compatibility with previous versions of this driver. + +pss_keep_settings + + This parameter can be used to specify whether you want the driver to reset +all emulations whenever its unloaded. This can be useful for those who are +sharing resources (io ports, IRQ's, DMA's) between different ISA cards. This +flag can also be useful in that future versions of this driver may reset all +emulations by default on the driver's unloading (as it probably should), so +specifying it now will ensure that all future versions of this driver will +continue to work as expected. The default value of this parameter is 1 to +retain full behavioral compatibility with previous versions of this driver. + +pss_firmware + + This parameter can be used to specify the file containing the firmware +code so that a user could tell the driver where that file is located instead +of having to put it in a predefined location with a predefined name.

The default values + offered by these programs are not necessarily valid. + + +THE BIGGEST MISTAKES YOU CAN MAKE +================================= + +1. Assuming that the card is Sound Blaster compatible when it's not. +-------------------------------------------------------------------- + +The number one mistake is to assume that your card is compatible with +Sound Blaster. Only the cards made by Creative Technology or which have +one or more chips labeled by Creative are SB compatible. In addition there +are few sound chipsets which are SB compatible in Linux such as ESS1688 or +Jazz16. Note that SB compatibility in DOS/Windows does _NOT_ mean anything +in Linux. + +IF YOU REALLY ARE 150% SURE YOU HAVE A SOUND BLASTER YOU CAN SKIP THE REST OF +THIS CHAPTER. + +For most other "supposed to be SB compatible" cards you have to use other +than SB drivers (see below). It is possible to get most sound cards to work +in SB mode but in general it's a complete waste of time. There are several +problems which you will encounter by using SB mode with cards that are not +truly SB compatible: + +- The SB emulation is at most SB Pro (DSP version 3.x) which means that +you get only 8 bit audio (there is always an another ("native") mode which +gives the 16 bit capability). The 8 bit only operation is the reason why +many users claim that sound quality in Linux is much worse than in DOS. +In addition some applications require 16 bit mode and they produce just +noise with a 8 bit only device. +- The card may work only in some cases but refuse to work most of the +time. The SB compatible mode always requires special initialization which is +done by the DOS/Windows drivers. This kind of cards work in Linux after +you have warm booted it after DOS but they don't work after cold boot +(power on or reset). +- You get the famous "DMA timed out" messages. Usually all SB clones have +software selectable IRQ and DMA settings. If the (power on default) values +currently used by the card don't match configuration of the driver you will +get the above error message whenever you try to record or play. There are +few other reasons to the DMA timeout message but using the SB mode seems +to be the most common cause. + +2. Trying to use a PnP (Plug & Play) card just like an ordinary sound card +-------------------------------------------------------------------------- + +Plug & Play is a protocol defined by Intel and Microsoft. It lets operating +systems to easily identify and reconfigure I/O ports, IRQs and DMAs of ISA +cards. The problem with PnP cards is that the standard Linux doesn't currently +(versions 2.1.x and earlier) don't support PnP. This means that you will have +to use some special tricks (see later) to get a PnP card alive. Many PnP cards +work after they have been initialized but this is not always the case. + +There are sometimes both PnP and non-PnP versions of the same sound card. +The non-PnP version is the original model which usually has been discontinued +more than an year ago. The PnP version has the same name but with "PnP" +appended to it (sometimes not). This causes major confusion since the non-PnP +model works with Linux but the PnP one doesn't. + +You should carefully check if "Plug & Play" or "PnP" is mentioned in the name +of the card or in the documentation or package that came with the card. +Everything described in the rest of this document is not necessarily valid for +PnP models of sound cards even you have managed to wake up the card properly. +Many PnP cards are simply too different from their non-PnP ancestors which are +covered by this document. + + +Cards that are not (fully) supported by this driver +=================================================== + +See http://www.opensound.com/ossfree for information about sound cards +to be supported in future. + + +How to use sound without recompiling kernel and/or sound driver +=============================================================== + +There is a commercial sound driver which comes in precompiled form and doesn't +require recompiling of the kernel. See http://www.4Front-tech.com/oss.html for +more info. + + +Configuring PnP cards +===================== + +New versions of most sound cards use the so-called ISA PnP protocol for +soft configuring their I/O, IRQ, DMA and shared memory resources. +Currently at least cards made by Creative Technology (SB32 and SB32AWE +PnP), Gravis (GUS PnP and GUS PnP Pro), Ensoniq (Soundscape PnP) and +Aztech (some Sound Galaxy models) use PnP technology. The CS4232/4236 audio +chip by Crystal Semiconductor (Intel Atlantis, HP Pavilion and many other +motherboards) is also based on PnP technology but there is a "native" driver +available for it (see information about CS4232 later in this document). + +PnP sound cards (as well as most other PnP ISA cards) are not supported +by this version of the driver . Proper +support for them should be released during 97 once the kernel level +PnP support is available. + +There is a method to get most of the PnP cards to work. The basic method +is the following: + +1) Boot DOS so the card's DOS drivers have a chance to initialize it. +2) _Cold_ boot to Linux by using "loadlin.exe". Hitting ctrl-alt-del +works with older machines but causes a hard reset of all cards on recent +(Pentium) machines. +3) If you have the sound driver in Linux configured properly, the card should +work now. "Proper" means that I/O, IRQ and DMA settings are the same as in +DOS. The hard part is to find which settings were used. See the documentation of +your card for more info. + +Windows 95 could work as well as DOS but running loadlin may be difficult. +Probably you should "shut down" your machine to MS-DOS mode before running it. + +Some machines have a BIOS utility for setting PnP resources. This is a good +way to configure some cards. In this case you don't need to boot DOS/Win95 +before starting Linux. + +Another way to initialize PnP cards without DOS/Win95 is a Linux based +PnP isolation tool. When writing this there is a pre alpha test version +of such a tool available from ftp://ftp.demon.co.uk/pub/unix/linux/utils. The +file is called isapnptools-*. Please note that this tool is just a temporary +solution which may be incompatible with future kernel versions having proper +support for PnP cards. There are bugs in setting DMA channels in earlier +versions of isapnptools so at least version 1.6 is required with sound cards. + +Yet another way to use PnP cards is to use (commercial) OSS/Linux drivers. See +http://www.opensound.com/linux.html for more info. This is probably the way you +should do it if you don't want to spend time recompiling the kernel and +required tools. + + +Read this before trying to configure the driver +=============================================== + +There are currently many cards that work with this driver. Some of the cards +have native support while others work since they emulate some other +card (usually SB, MSS/WSS and/or MPU401). The following cards have native +support in the driver. Detailed instructions for configuring these cards +will be given later in this document. + +Pro Audio Spectrum 16 (PAS16) and compatibles: + Pro Audio Spectrum 16 + Pro Audio Studio 16 + Logitech Sound Man 16 + NOTE! The original Pro Audio Spectrum as well as the PAS+ are not + and will not be supported by the driver. + +Media Vision Jazz16 based cards + Pro Sonic 16 + Logitech SoundMan Wave + (Other Jazz based cards should work but I don't have any reports + about them). + +Sound Blasters + SB 1.0 to 2.0 + SB Pro + SB 16 + SB32/64/AWE + Configure SB32/64/AWE just like SB16. See lowlevel/README.awe + for information about using the wave table synth. + NOTE! AWE63/Gold and 16/32/AWE "PnP" cards need to be activated + using isapnptools before they work with OSS/Free. + SB16 compatible cards by other manufacturers than Creative. + You have been fooled since there are _no_ SB16 compatible + cards on the market (as of May 1997). It's likely that your card + is compatible just with SB Pro but there is also a non-SB- + compatible 16 bit mode. Usually it's MSS/WSS but it could also + be a proprietary one like MV Jazz16 or ESS ES688. OPTi + MAD16 chips are very common in so called "SB 16 bit cards" + (try with the MAD16 driver). + + ====================================================================== + "Supposed to be SB compatible" cards. + Forget the SB compatibility and check for other alternatives + first. The only cards that work with the SB driver in + Linux have been made by Creative Technology (there is at least + one chip on the card with "CREATIVE" printed on it). The + only other SB compatible chips are ESS and Jazz16 chips + (maybe ALSxxx chips too but they probably don't work). + Most other "16 bit SB compatible" cards such as "OPTi/MAD16" or + "Crystal" are _NOT_ SB compatible in Linux. + + Practically all sound cards have some kind of SB emulation mode + in addition to their native (16 bit) mode. In most cases this + (8 bit only) SB compatible mode doesn't work with Linux. If + you get it working it may cause problems with games and + applications which require 16 bit audio. Some 16 bit only + applications don't check if the card actually supports 16 bits. + They just dump 16 bit data to a 8 bit card which produces just + noise. + + In most cases the 16 bit native mode is supported by Linux. + Use the SB mode with "clones" only if you don't find anything + better from the rest of this doc. + ====================================================================== + +Gravis Ultrasound (GUS) + GUS + GUS + the 16 bit option + GUS MAX + GUS ACE (No MIDI port and audio recording) + GUS PnP (with RAM) + +MPU-401 and compatibles + The driver works both with the full (intelligent mode) MPU-401 + cards (such as MPU IPC-T and MQX-32M) and with the UART only + dumb MIDI ports. MPU-401 is currently the most common MIDI + interface. Most sound cards are compatible with it. However, + don't enable MPU401 mode blindly. Many cards with native support + in the driver have their own MPU401 driver. Enabling the standard one + will cause a conflict with these cards. So check if your card is + in the list of supported cards before enabling MPU401. + +Windows Sound System (MSS/WSS) + Even when Microsoft has discontinued their own Sound System card + they managed to make it a standard. MSS compatible cards are based on + a codec chip which is easily available from at least two manufacturers + (AD1848 by Analog Devices and CS4231/CS4248 by Crystal Semiconductor). + Currently most sound cards are based on one of the MSS compatible codec + chips. The CS4231 is used in the high quality cards such as GUS MAX, + MediaTrix AudioTrix Pro and TB Tropez (GUS MAX is not MSS compatible). + + Having a AD1848, CS4248 or CS4231 codec chip on the card is a good + sign. Even if the card is not MSS compatible, it could be easy to write + support for it. Note also that most MSS compatible cards + require special boot time initialization which may not be present + in the driver. Also, some MSS compatible cards have native support. + Enabling the MSS support with these cards is likely to + cause a conflict. So check if your card is listed in this file before + enabling the MSS support. + +Yamaha FM synthesizers (OPL2, OPL3 (not OPL3-SA) and OPL4) + Most sound cards have a FM synthesizer chip. The OPL2 is a 2 + operator chip used in the original AdLib card. Currently it's used + only in the cheapest (8 bit mono) cards. The OPL3 is a 4 operator + FM chip which provides better sound quality and/or more available + voices than the OPL2. The OPL4 is a new chip that has an OPL3 and + a wave table synthesizer packed onto the same chip. The driver supports + just the OPL3 mode directly. Most cards with an OPL4 (like + SM Wave and AudioTrix Pro) support the OPL4 mode using MPU401 + emulation. Writing a native OPL4 support is difficult + since Yamaha doesn't give information about their sample ROM chip. + + Enable the generic OPL2/OPL3 FM synthesizer support if your + card has a FM chip made by Yamaha. Don't enable it if your card + has a software (TRS) based FM emulator. + + ---------------------------------------------------------------- + NOTE! OPL3-SA is different chip than the ordinary OPL3. In addition + to the FM synth this chip has also digital audio (WSS) and + MIDI (MPU401) capabilities. Support for OPL3-SA is described below. + ---------------------------------------------------------------- + +Yamaha OPL3-SA1 + + Yamaha OPL3-SA1 (YMF701) is an audio controller chip used on some + (Intel) motherboards and on cheap sound cards. It should not be + confused with the original OPL3 chip (YMF278) which is entirely + different chip. OPL3-SA1 has support for MSS, MPU401 and SB Pro + (not used in OSS/Free) in addition to the OPL3 FM synth. + + There are also chips called OPL3-SA2, OPL3-SA3, ..., OPL3SA-N. They + are PnP chips and will not work with the OPL3-SA1 driver. You should + use the standard MSS, MPU401 and OPL3 options with these chips and to + activate the card using isapnptools. + +4Front Technologies SoftOSS + + SoftOSS is a software based wave table emulation which works with + any 16 bit stereo sound card. Due to its nature a fast CPU is + required (P133 is minimum). Although SoftOSS does _not_ use MMX + instructions it has proven out that recent processors (which appear + to have MMX) perform significantly better with SoftOSS than earlier + ones. For example a P166MMX beats a PPro200. SoftOSS should not be used + on 486 or 386 machines. + + The amount of CPU load caused by SoftOSS can be controlled by + selecting the CONFIG_SOFTOSS_RATE and CONFIG_SOFTOSS_VOICES + parameters properly (they will be prompted by make config). It's + recommended to set CONFIG_SOFTOSS_VOICES to 32. If you have a + P166MMX or faster (PPro200 is not faster) you can set + CONFIG_SOFTOSS_RATE to 44100 (kHz). However with slower systems it + recommended to use sampling rates around 22050 or even 16000 kHz. + Selecting too high values for these parameters may hang your + system when playing MIDI files with hight degree of polyphony + (number of concurrently playing notes). It's also possible to + decrease CONFIG_SOFTOSS_VOICES. This makes it possible to use + higher sampling rates. However using fewer voices decreases + playback quality more than decreasing the sampling rate. + + SoftOSS keeps the samples loaded on the system's RAM so much RAM is + required. SoftOSS should never be used on machines with less than 16 MB + of RAM since this is potentially dangerous (you may accidentally run out + of memory which probably crashes the machine). + + SoftOSS implements the wave table API originally designed for GUS. For + this reason all applications designed for GUS should work (at least + after minor modifications). For example gmod/xgmod and playmidi -g are + known to work. + + To work SoftOSS will require GUS compatible + patch files to be installed on the system (in /dos/ultrasnd/midi). You + can use the public domain MIDIA patchset available from several ftp + sites. + + ********************************************************************* + IMPORTANT NOTICE! The original patch set distributed with the Gravis + Ultrasound card is not in public domain (even though it's available from + some FTP sites). You should contact Voice Crystal (www.voicecrystal.com) + if you like to use these patches with SoftOSS included in OSS/Free. + ********************************************************************* + +PSS based cards (AD1848 + ADSP-2115 + Echo ESC614 ASIC) + Analog Devices and Echo Speech have together defined a sound card + architecture based on the above chips. The DSP chip is used + for emulation of SB Pro, FM and General MIDI/MT32. + + There are several cards based on this architecture. The most known + ones are Orchid SW32 and Cardinal DSP16. + + The driver supports downloading DSP algorithms to these cards. + + NOTE! You will have to use the "old" config script when configuring + PSS cards. + +MediaTrix AudioTrix Pro + The ATP card is built around a CS4231 codec and an OPL4 synthesizer + chips. The OPL4 mode is supported by a microcontroller running a + General MIDI emulator. There is also a SB 1.5 compatible playback mode. + +Ensoniq SoundScape and compatibles + Ensoniq has designed a sound card architecture based on the + OTTO synthesizer chip used in their professional MIDI synthesizers. + Several companies (including Ensoniq, Reveal and Spea) are selling + cards based on this architecture. + + NOTE! The SoundScape PnP is not supported by OSS/Free. Ensoniq VIVO and + VIVO90 cards are not compatible with Soundscapes so the Soundscape + driver will not work with them. You may want to use OSS/Linux with these + cards. + +OPTi MAD16 and Mozart based cards + The Mozart (OAK OTI-601), MAD16 (OPTi 82C928), MAD16 Pro (OPTi 82C929), + OPTi 82C924/82C925 (in _non_ PnP mode) and OPTi 82C930 interface + chips are used in many different sound cards, including some + cards by Reveal miro and Turtle Beach (Tropez). The purpose of these + chips is to connect other audio components to the PC bus. The + interface chip performs address decoding for the other chips. + NOTE! Tropez Plus is not MAD16 but CS4232 based. + NOTE! MAD16 PnP cards (82C924, 82C925, 82C931) are not MAD16 compatible + in the PnP mode. You will have to use them in MSS mode after having + initialized them using isapnptools or DOS. 82C931 probably requires + initialization using DOS/Windows (running isapnptools is not enough). + It's possible to use 82C931 with OSS/Free by jumpering it to non-PnP + mode (provided that the card has a jumper for this). In non-PnP mode + 82C931 is compatible with 82C930 and should work with the MAD16 driver + (without need to use isapnptools or DOS to initialize it). All OPTi + chips are supported by OSS/Linux (both in PnP and non-PnP modes). + +Audio Excel DSP16 + Support for this card was written by Riccardo Faccetti + (riccardo@cdc8g5.cdc.polimi.it). The AEDSP16 driver included in + the lowlevel/ directory. To use it you should enable the + "Additional low level drivers" option. + +Crystal CS4232 and CS4236 based cards such as AcerMagic S23, TB Tropez _Plus_ and + many PC motherboards (Compaq, HP, Intel, ...) + CS4232 is a PnP multimedia chip which contains a CS3231A codec, + SB and MPU401 emulations. There is support for OPL3 too. + Unfortunately the MPU401 mode doesn't work (I don't know how to + initialize it). CS4236 is an enhanced (compatible) version of CS4232. + NOTE! Don't ever try to use isapnptools with CS4232 since this will just + freeze your machine (due to chip bugs). If you have problems in getting + CS4232 working you could try initializing it with DOS (CS4232C.EXE) and + then booting Linux using loadlin. CS4232C.EXE loads a secret firmware + patch which is not documented by Crystal. + +Turtle Beach Maui and Tropez "classic" + This driver version supports sample, patch and program loading commands + described in the Maui/Tropez User's manual. + There is now full initialization support too. The audio side of + the Tropez is based on the MAD16 chip (see above). + NOTE! Tropez Plus is different card than Tropez "classic" and will not + work fully in Linux. You can get audio features working by configuring + the card as a CS4232 based card (above). + + +Jumpers and software configuration +================================== + +Some of the earliest sound cards were jumper configurable. You have to +configure the driver use I/O, IRQ and DMA settings +that match the jumpers. Just few 8 bit cards are fully jumper +configurable (SB 1.x/2.x, SB Pro and clones). +Some cards made by Aztech have an EEPROM which contains the +config info. These cards behave much like hardware jumpered cards. + +Most cards have jumper for the base I/O address but other parameters +are software configurable. Sometimes there are few other jumpers too. + +Latest cards are fully software configurable or they are PnP ISA +compatible. There are no jumpers on the board. + +The driver handles software configurable cards automatically. Just configure +the driver to use I/O, IRQ and DMA settings which are known to work. +You could usually use the same values than with DOS and/or Windows. +Using different settings is possible but not recommended since it may cause +some trouble (for example when warm booting from an OS to another or +when installing new hardware to the machine). + +Sound driver sets the soft configurable parameters of the card automatically +during boot. Usually you don't need to run any extra initialization +programs when booting Linux but there are some exceptions. See the +card-specific instructions below for more info. + +The drawback of software configuration is that the driver needs to know +how the card must be initialized. It cannot initialize unknown cards +even if they are otherwise compatible with some other cards (like SB, +MPU401 or Windows Sound System). + + +What if your card was not listed above? +======================================= + +The first thing to do is to look at the major IC chips on the card. +Many of the latest sound cards are based on some standard chips. If you +are lucky, all of them could be supported by the driver. The most common ones +are the OPTi MAD16, Mozart, SoundScape (Ensoniq) and the PSS architectures +listed above. Also look at the end of this file for list of unsupported +cards and the ones which could be supported later. + +The last resort is to send _exact_ name and model information of the card +to me together with a list of the major IC chips (manufactured, model) to +me. I could then try to check if your card looks like something familiar. + +There are many more cards in the world than listed above. The first thing to +do with these cards is to check if they emulate some other card or interface +such as SB, MSS and/or MPU401. In this case there is a chance to get the +card to work by booting DOS before starting Linux (boot DOS, hit ctrl-alt-del +and boot Linux without hard resetting the machine). In this method the +DOS based driver initializes the hardware to use known I/O, IRQ and DMA +settings. If sound driver is configured to use the same settings, everything +should work OK. + + +Configuring sound driver (with Linux) +===================================== + +The sound driver is currently distributed as part of the Linux kernel. The +files are in /usr/src/linux/drivers/sound/. + +**************************************************************************** +* ALWAYS USE THE SOUND DRIVER VERSION WHICH IS DISTRIBUTED WITH * +* THE KERNEL SOURCE PACKAGE YOU ARE USING. SOME ALPHA AND BETA TEST * +* VERSIONS CAN BE INSTALLED FROM A SEPARATELY DISTRIBUTED PACKAGE * +* BUT CHECK THAT THE PACKAGE IS NOT MUCH OLDER (OR NEWER) THAN THE * +* KERNEL YOU ARE USING. IT'S POSSIBLE THAT THE KERNEL/DRIVER * +* INTERFACE CHANGES BETWEEN KERNEL RELEASES WHICH MAY CAUSE SOME * +* INCOMPATIBILITY PROBLEMS. * +* * +* IN CASE YOU INSTALL A SEPARATELY DISTRIBUTED SOUND DRIVER VERSION, * +* BE SURE TO REMOVE OR RENAME THE OLD SOUND DRIVER DIRECTORY BEFORE * +* INSTALLING THE NEW ONE. LEAVING OLD FILES TO THE SOUND DRIVER * +* DIRECTORY _WILL_ CAUSE PROBLEMS WHEN THE DRIVER IS USED OR * +* COMPILED. * +**************************************************************************** + +To configure the driver, run "make config" in the kernel source directory +(/usr/src/linux). Answer "y" or "m" to the question about Sound card support +(after the questions about mouse, CD-ROM, ftape, etc. support). Questions +about options for sound will then be asked. + +After configuring the kernel and sound driver and compile the kernel +following instructions in the kernel README. + +The sound driver configuration dialog +------------------------------------- + +Sound configuration starts by making some yes/no questions. Be careful +when answering to these questions since answering y to a question may +prevent some later ones from being asked. For example don't answer y to +the first question (PAS16) if you don't really have a PAS16. Don't enable +more cards than you really need since they just consume memory. Also +some drivers (like MPU401) may conflict with your SCSI controller and +prevent kernel from booting. If you card was in the list of supported +cards (above), please look at the card specific config instructions +(later in this file) before starting to configure. Some cards must be +configured in way which is not obvious. + +So here is the beginning of the config dialog. Answer 'y' or 'n' to these +questions. The default answer is shown so that (y/n) means 'y' by default and +(n/y) means 'n'. To use the default value, just hit ENTER. But be careful +since using the default _doesn't_ guarantee anything. + +Note also that all questions may not be asked. The configuration program +may disable some questions depending on the earlier choices. It may also +select some options automatically as well. + + "ProAudioSpectrum 16 support", + - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_, + Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that + you read the above list correctly). Don't answer 'y' if you + have some other card made by Media Vision or Logitech since they + are not PAS16 compatible. + NOTE! Since 3.5-beta10 you need to enable SB support (next question) + if you want to use the SB emulation of PAS16. It's also possible to + the emulation if you want to use a true SB card together with PAS16 + (there is another question about this that is asked later). + "Sound Blaster support", + - Answer 'y' if you have an original SB card made by Creative Labs + or a full 100% hardware compatible clone (like Thunderboard or + SM Games). If your card was in the list of supported cards (above), + please look at the card specific instructions later in this file + before answering this question. For an unknown card you may answer + 'y' if the card claims to be SB compatible. + Enable this option also with PAS16 (changed since v3.5-beta9). + + Don't enable SB if you have a MAD16 or Mozart compatible card. + + "Generic OPL2/OPL3 FM synthesizer support", + - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4). + Answering 'y' is usually a safe and recommended choice. However some + cards may have software (TSR) FM emulation. Enabling FM support + with these cards may cause trouble. However I don't currently know + such cards. + "Gravis Ultrasound support", + - Answer 'y' if you have GUS or GUS MAX. Answer 'n' if you don't + have GUS since the GUS driver consumes much memory. + Currently I don't have experiences with the GUS ACE so I don't + know what to answer with it. + "MPU-401 support (NOT for SB16)", + - Be careful with this question. The MPU401 interface is supported + by almost any sound card today. However some natively supported cards + have their own driver for MPU401. Enabling the MPU401 option with + these cards will cause a conflict. Also enabling MPU401 on a system + that doesn't really have a MPU401 could cause some trouble. If your + card was in the list of supported cards (above), please look at + the card specific instructions later in this file. + + In MOST cases this MPU401 driver should only be used with "true" + MIDI-only MPU401 professional cards. In most other cases there + is another way to get the MPU401 compatible interface of a + sound card to work. + Support for the MPU401 compatible MIDI port of SB16, ESS1688 + and MV Jazz16 cards is included in the SB driver. Use it instead + of this separate MPU401 driver with these cards. As well + Soundscape, PSS and Maui drivers include their own MPU401 + options. + + It's safe to answer 'y' if you have a true MPU401 MIDI interface + card. + "6850 UART Midi support", + - It's safe to answer 'n' to this question in all cases. The 6850 + UART interface is so rarely used. + "PSS (ECHO-ADI2111) support", + - Answer 'y' only if you have Orchid SW32, Cardinal DSP16 or some + other card based on the PSS chipset (AD1848 codec + ADSP-2115 + DSP chip + Echo ESC614 ASIC CHIP). + "16 bit sampling option of GUS (_NOT_ GUS MAX)", + - Answer 'y' if you have installed the 16 bit sampling daughtercard + to your GUS. Answer 'n' if you have GUS MAX. Enabling this option + disables GUS MAX support. + "GUS MAX support", + - Answer 'y' only if you have a GUS MAX. + "Microsoft Sound System support", + - Again think carefully before answering 'y' to this question. It's + safe to answer 'y' in case you have the original Windows Sound + System card made by Microsoft or Aztech SG 16 Pro (or NX16 Pro). + Also you may answer 'y' in case your card was not listed earlier + in this file. For cards having native support in the driver, consult + the card specific instructions later in this file. Some drivers + have their own MSS support and enabling this option will cause a + conflict. + Note! The MSS driver permits configuring two DMA channels. This is a + "nonstandard" feature and works only with very few cards (if any). + In most cases the second DMA channel should be disabled or set to + the same channel than the first one. Trying to configure two separate + channels with cards that don't support this feature will prevent + audio (at least recording) from working. + "Ensoniq Soundscape support", + - Answer 'y' if you have a sound card based on the Ensoniq SoundScape + chipset. Such cards are being manufactured at least by Ensoniq, + Spea and Reveal (note that Reveal makes other cards also). The oldest + cards made by Spea don't work properly with Linux. + Soundscape PnP as well as Ensoniq VIVO work only with the commercial + OSS/Linux version. + "MediaTrix AudioTrix Pro support", + - Answer 'y' if you have the AudioTrix Pro. + "Support for MAD16 and/or Mozart based cards", + - Answer y if your card has a Mozart (OAK OTI-601) or MAD16 + (OPTi 82C928, 82C929, 82C924/82C925 or 82C930) audio interface chip. + These chips are + currently quite common so it's possible that many no-name cards + have one of them. In addition the MAD16 chip is used in some + cards made by known manufacturers such as Turtle Beach (Tropez), + Reveal (some models) and Diamond (some recent models). + Note OPTi 82C924 and 82C925 are MAD16 compatible only in non PnP + mode (jumper selectable on many cards). + "Support for TB Maui" + - This enables TB Maui specific initialization. Works with TB Maui + and TB Tropez (may not work with Tropez Plus). + + +Then the configuration program asks some y/n questions about the higher +level services. It's recommended to answer 'y' to each of these questions. +Answer 'n' only if you know you will not need the option. + + "MIDI interface support", + - Answering 'n' disables /dev/midi## devices and access to any + MIDI ports using /dev/sequencer and /dev/music. This option + also affects any MPU401 and/or General MIDI compatible devices. + "FM synthesizer (YM3812/OPL-3) support", + - Answer 'y' here. + "/dev/sequencer support", + - Answering 'n' disables /dev/sequencer and /dev/music. + +Entering the I/O, IRQ and DMA config parameters +----------------------------------------------- + +After the above questions the configuration program prompts for the +card specific configuration information. Usually just a set of +I/O address, IRQ and DMA numbers are asked. With some cards the program +asks for some files to be used during initialization of the card. For example +many cards have a DSP chip or microprocessor which must be initialized by +downloading a program (microcode) file to the card. + +Instructions for answering these questions are given in the next section. + + +Card specific information +========================= + +This section gives additional instructions about configuring some cards. +Please refer manual of your card for valid I/O, IRQ and DMA numbers. Using +the same settings with DOS/Windows and Linux is recommended. Using +different values could cause some problems when switching between +different operating systems. + +Sound Blasters (the original ones by Creative) +--------------------------------------------- + +NOTE! Check if you have a PnP Sound Blaster (cards sold after summer 1995 + are almost certainly PnP ones). With PnP cards you should use isapnptools + to activate them (see above). + +It's possible to configure these cards to use different I/O, IRQ and +DMA settings. Since the possible/default settings have changed between various +models, you have to consult manual of your card for the proper ones. It's +a good idea to use the same values than with DOS/Windows. With SB and SB Pro +it's the only choice. SB16 has software selectable IRQ and DMA channels but +using different values with DOS and Linux is likely to cause troubles. The +DOS driver is not able to reset the card properly after warm boot from Linux +if Linux has used different IRQ or DMA values. + +The original (steam) Sound Blaster (versions 1.x and 2.x) use always +DMA1. There is no way to change it. + +The SB16 needs two DMA channels. A 8 bit one (1 or 3) is required for +8 bit operation and a 16 bit one (5, 6 or 7) for the 16 bit mode. In theory +it's possible to use just one (8 bit) DMA channel by answering the 8 bit +one when the configuration program asks for the 16 bit one. This may work +in some systems but is likely to cause terrible noise on some other systems. + +It's possible to use two SB16/32/64 at the same time. To do this you should +first configure OSS/Free for one card. Then edit local.h manually and define +SB2_BASE, SB2_IRQ, SB2_DMA and SB2_DMA2 for the second one. You can't get +the OPL3, MIDI and EMU8000 devices of the second card to work. If you are +going to use two PnP Sound Blasters, ensure that they are of different model +and have different PnP IDs. There is no way to get two cards with the same +card ID and serial number to work. The easiest way to check this is trying +if isapnptools can see both cards or just one. + +NOTE! Don't enable the SM Games option (asked by the configuration program) + if you are not 101% sure that your card is a Logitech Soundman Games + (not a SM Wave or SM16). + +SB Clones +--------- + +First of all: There are no SB16 clones. There are SB Pro clones with a +16 bit mode which is not SB16 compatible. The most likely alternative is that +the 16 bit mode means MSS/WSS. + +There are just a few fully 100% hardware SB or SB Pro compatible cards. +I know just Thunderboard and SM Games. Other cards require some kind of +hardware initialization before they become SB compatible. Check if your card +was listed in the beginning of this file. In this case you should follow +instructions for your card later in this file. + +For other not fully SB clones you may try initialization using DOS in +the following way: + + - Boot DOS so that the card specific driver gets run. + - Hit ctrl-alt-del (or use loadlin) to boot Linux. Don't + switch off power or press the reset button. + - If you use the same I/O, IRQ and DMA settings in Linux, the + card should work. + +If your card is both SB and MSS compatible, I recommend using the MSS mode. +Most cards of this kind are not able to work in the SB and the MSS mode +simultaneously. Using the MSS mode provides 16 bit recording and playback. + +ProAudioSpectrum 16 and compatibles +----------------------------------- + +PAS16 has a SB emulation chip which can be used together with the native +(16 bit) mode of the card. To enable this emulation you should configure +the driver to have SB support too (this has been changed since version +3.5-beta9 of this driver). + +With current driver versions it's also possible to use PAS16 together with +another SB compatible card. In this case you should configure SB support +for the other card and to disable the SB emulation of PAS16 (there is a +separate questions about this). + +With PAS16 you can use two audio device files at the same time. /dev/dsp (and +/dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and +/dev/audio1) is connected to the SB emulation (8 bit mono only). + +Gravis Ultrasound +----------------- + +There are many different revisions of the Ultrasound card (GUS). The +earliest ones (pre 3.7) don't have a hardware mixer. With these cards +the driver uses a software emulation for synth and pcm playbacks. It's +also possible to switch some of the inputs (line in, mic) off by setting +mixer volume of the channel level below 10%. For recording you have +to select the channel as a recording source and to use volume above 10%. + +GUS 3.7 has a hardware mixer. + +GUS MAX and the 16 bit sampling daughtercard have a CS4231 codec chip which +also contains a mixer. + +Configuring GUS is simple. Just enable the GUS support and GUS MAX or +the 16 bit daughtercard if you have them. Note that enabling the daughter +card disables GUS MAX driver. + +NOTE for owners of the 16 bit daughtercard: By default the daughtercard +uses /dev/dsp (and /dev/audio). Command "ln -sf /dev/dsp1 /dev/dsp" +selects the daughter card as the default device. + +With just the standard GUS enabled the configuration program prompts +for the I/O, IRQ and DMA numbers for the card. Use the same values than +with DOS. + +With the daughter card option enabled you will be prompted for the I/O, +IRQ and DMA numbers for the daughter card. You have to use different I/O +and DMA values than for the standard GUS. The daughter card permits +simultaneous recording and playback. Use /dev/dsp (the daughtercard) for +recording and /dev/dsp1 (GUS GF1) for playback. + +GUS MAX uses the same I/O address and IRQ settings than the original GUS +(GUS MAX = GUS + a CS4231 codec). In addition an extra DMA channel may be used. +Using two DMA channels permits simultaneous playback using two devices +(dev/dsp0 and /dev/dsp1). The second DMA channel is required for +full duplex audio. +To enable the second DMA channels, give a valid DMA channel when the config +program asks for the GUS MAX DMA (entering -1 disables the second DMA). +Using 16 bit DMA channels (5,6 or 7) is recommended. + +If you have problems in recording with GUS MAX, you could try to use +just one 8 bit DMA channel. Recording will not work with one DMA +channel if it's a 16 bit one. + +Microphone input of GUS MAX is connected to mixer in little bit nonstandard +way. There is actually two microphone volume controls. Normal "mic" controls +only recording level. Mixer control "speaker" is used to control volume of +microphone signal connected directly to line/speaker out. So just decrease +volume of "speaker" if you have problems with microphone feedback. + +GUS ACE works too but any attempt to record or to use the MIDI port +will fail. + +GUS PnP (with RAM) is partially supported but it needs to be initialized using +DOS or isapnptools before starting the driver. + +MPU401 and Windows Sound System +------------------------------- + +Again. Don't enable these options in case your card is listed +somewhere else in this file. + +Configuring these cards is obvious (or it should be). With MSS +you should probably enable the OPL3 synth also since +most MSS compatible cards have it. However check that this is true +before enabling OPL3. + +Sound driver supports more than one MPU401 compatible cards at the same time +but the config program asks config info for just the first of them. +Adding the second or third MPU interfaces must be done manually by +editing sound/local.h (after running the config program). Add defines for +MPU2_BASE & MPU2_IRQ (and MPU3_BASE & MPU3_IRQ) to the file. + +CAUTION! + +The default I/O base of Adaptec AHA-1542 SCSI controller is 0x330 which +is also the default of the MPU401 driver. Don't configure the sound driver to +use 0x330 as the MPU401 base if you have a AHA1542. The kernel will not boot +if you make this mistake. + +PSS +--- + +Even the PSS cards are compatible with SB, MSS and MPU401, you must not +enable these options when configuring the driver. The configuration +program handles these options itself. (You may use the SB, MPU and MSS options +together with PSS if you have another card on the system). + +The PSS driver enables MSS and MPU401 modes of the card. SB is not enabled +since it doesn't work concurrently with MSS. The driver loads also a +DSP algorithm which is used to for the general MIDI emulation. The +algorithm file (.ld) is read by the config program and written to a +file included when the pss.c is compiled. For this reason the config +program asks if you want to download the file. Use the genmidi.ld file +distributed with the DOS/Windows drivers of the card (don't use the mt32.ld). +With some cards the file is called 'synth.ld'. You must have access to +the file when configuring the driver. The easiest way is to mount the DOS +partition containing the file with Linux. + +It's possible to load your own DSP algorithms and run them with the card. +Look at the directory pss_test of snd-util-3.0.tar.gz for more info. + +AudioTrix Pro +------------- + +You have to enable the OPL3 and SB (not SB Pro or SB16) drivers in addition +to the native AudioTrix driver. Don't enable MSS or MPU drivers. + +Configuring ATP is little bit tricky since it uses so many I/O, IRQ and +DMA numbers. Using the same values than with DOS/Win is a good idea. Don't +attempt to use the same IRQ or DMA channels twice. + +The SB mode of ATP is implemented so the ATP driver just enables SB +in the proper address. The SB driver handles the rest. You have to configure +both the SB driver and the SB mode of ATP to use the same IRQ, DMA and I/O +settings. + +Also the ATP has a microcontroller for the General MIDI emulation (OPL4). +For this reason the driver asks for the name of a file containing the +microcode (TRXPRO.HEX). This file is usually located in the directory +where the DOS drivers were installed. You must have access to this file +when configuring the driver. + +If you have the effects daughtercard, it must be initialized by running +the setfx program of snd-util-3.0.tar.gz package. This step is not required +when using the (future) binary distribution version of the driver. + +Ensoniq SoundScape +------------------ + +NOTE! The new PnP SoundScape is not supported yet. Soundscape compatible + cards made by Reveal don't work with Linux. They use older revision + of the Soundscape chipset which is not fully compatible with + newer cards made by Ensoniq. + +The SoundScape driver handles initialization of MSS and MPU supports +itself so you don't need to enable other drivers than SoundScape +(enable also the /dev/dsp, /dev/sequencer and MIDI supports). + +!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! +!!!!! !!!! +!!!!! NOTE! Before version 3.5-beta6 there WERE two sets of audio !!!! +!!!!! device files (/dev/dsp0 and /dev/dsp1). The first one WAS !!!! +!!!!! used only for card initialization and the second for audio !!!! +!!!!! purposes. It WAS required to change /dev/dsp (a symlink) to !!!! +!!!!! point to /dev/dsp1. !!!! +!!!!! !!!! +!!!!! This is not required with OSS versions 3.5-beta6 and later !!!! +!!!!! since there is now just one audio device file. Please !!!! +!!!!! change /dev/dsp to point back to /dev/dsp0 if you are !!!! +!!!!! upgrading from an earlier driver version using !!!! +!!!!! (cd /dev;rm dsp;ln -s dsp0 dsp). !!!! +!!!!! !!!! +!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! + +The configuration program asks one DMA channel and two interrupts. One IRQ +and one DMA is used by the MSS codec. The second IRQ is required for the +MPU401 mode (you have to use different IRQs for both purposes). +There were earlier two DMA channels for SoundScape but the current driver +version requires just one. + +The SoundScape card has a Motorola microcontroller which must initialized +_after_ boot (the driver doesn't initialize it during boot). +The initialization is done by running the 'ssinit' program which is +distributed in the snd-util-3.0.tar.gz package. You have to edit two +defines in the ssinit.c and then compile the program. You may run ssinit +manually (after each boot) or add it to /etc/rc.d/rc.local. + +The ssinit program needs the microcode file that comes with the DOS/Windows +driver of the card. You will need to use version 1.30.00 or later +of the microcode file (sndscape.co0 or sndscape.co1 depending on +your card model). THE OLD sndscape.cod WILL NOT WORK. IT WILL HANG YOUR +MACHINE. The only way to get the new microcode file is to download +and install the DOS/Windows driver from ftp://ftp.ensoniq.com/pub. + +Then you have to select the proper microcode file to use: soundscape.co0 +is the right one for most cards and sndscape.co1 is for few (older) cards +made by Reveal and/or Spea. The driver has capability to detect the card +version during boot. Look at the boot log messages in /var/adm/messages +and locate the sound driver initialization message for the SoundScape +card. If the driver displays string <Ensoniq Soundscape (old)>, you have +an old card and you will need to use sndscape.co1. For other cards use +soundscape.co0. New Soundscape revisions such as Elite and PnP use +code files with higher numbers (.co2, .co3, etc.). + +NOTE! Ensoniq Soundscape VIVO is not compatible with other Soundscape cards. + Currently it's possible to use it in Linux only with OSS/Linux + drivers. + +Check /var/adm/messages after running ssinit. The driver prints +the board version after downloading the microcode file. That version +number must match the number in the name of the microcode file (extension). + +Running ssinit with a wrong version of the sndscape.co? file is not +dangerous as long as you don't try to use a file called sndscape.cod. +If you have initialized the card using a wrong microcode file (sounds +are terrible), just modify ssinit.c to use another microcode file and try +again. It's possible to use an earlier version of sndscape.co[01] but it +may sound weird. + +MAD16 (Pro) and Mozart +---------------------- + +You need to enable just the MAD16 /Mozart support when configuring +the driver. _Don't_ enable SB, MPU401 or MSS. However you will need the +/dev/audio, /dev/sequencer and MIDI supports. + +Mozart and OPTi 82C928 (the original MAD16) chips don't support +MPU401 mode so enter just 0 when the configuration program asks the +MPU/MIDI I/O base. The MAD16 Pro (OPTi 82C929) and 82C930 chips have MPU401 +mode. + +TB Tropez is based on the 82C929 chip. It has two MIDI ports. +The one connected to the MAD16 chip is the second one (there is a second +MIDI connector/pins somewhere??). If you have not connected the second MIDI +port, just disable the MIDI port of MAD16. The 'Maui' compatible synth of +Tropez is jumper configurable and not connected to the MAD16 chip (the +Maui driver can be used with it). + +Some MAD16 based cards may cause feedback, whistle or terrible noise if the +line3 mixer channel is turned too high. This happens at least with Shuttle +Sound System. Current driver versions set volume of line3 low enough so +this should not be a problem. + +If you have a MAD16 card which have an OPL4 (FM + Wave table) synthesizer +chip (_not_ an OPL3), you have to append a line containing #define MAD16_OPL4 +to the file linux/drivers/sound/local.h (after running make config). + +MAD16 cards having a CS4231 codec support full duplex mode. This mode +can be enabled by configuring the card to use two DMA channels. Possible +DMA channel pairs are: 0&1, 1&0 and 3&0. + +NOTE! Cards having an OPTi 82C924/82C925 chip work with OSS/Free only in +non-PnP mode (usually jumper selectable). The PnP mode is supported only +by OSS/Linux. + +MV Jazz (ProSonic) +------------------ + +The Jazz16 driver is just a hack made to the SB Pro driver. However it works +fairly well. You have to enable SB, SB Pro (_not_ SB16) and MPU401 supports +when configuring the driver. The configuration program asks later if you +want support for MV Jazz16 based cards (after asking SB base address). Answer +'y' here and the driver asks the second (16 bit) DMA channel. + +The Jazz16 driver uses the MPU401 driver in a way which will cause +problems if you have another MPU401 compatible card. In this case you must +give address of the Jazz16 based MPU401 interface when the config +program prompts for the MPU401 information. Then look at the MPU401 +specific section for instructions about configuring more than one MPU401 cards. + +Logitech Soundman Wave +---------------------- + +Read the above MV Jazz specific instructions first. + +The Logitech SoundMan Wave (don't confuse this with the SM16 or SM Games) is +a MV Jazz based card which has an additional OPL4 based wave table +synthesizer. The OPL4 chip is handled by an on board microcontroller +which must be initialized during boot. The config program asks if +you have a SM Wave immediately after asking the second DMA channel of jazz16. +If you answer 'y', the config program will ask name of the file containing +code to be loaded to the microcontroller. The file is usually called +MIDI0001.BIN and it's located in the DOS/Windows driver directory. The file +may also be called as TSUNAMI.BIN or something else (older cards?). + +The OPL4 synth will be inaccessible without loading the microcontroller code. + +Also remember to enable SB MPU401 support if you want to use the OPL4 mode. +(Don't enable the 'normal' MPU401 device as with some earlier driver +versions (pre 3.5-alpha8)). + +NOTE! Don't answer 'y' when the driver asks about SM Games support + (the next question after the MIDI0001.BIN name). However + answering 'y' doesn't cause damage your computer so don't panic. + +Sound Galaxies +-------------- + +There are many different Sound Galaxy cards made by Aztech. The 8 bit +ones are fully SB or SB Pro compatible and there should be no problems +with them. + +The older 16 bit cards (SG Pro16, SG NX Pro16, Nova and Lyra) have +an EEPROM chip for storing the configuration data. There is a microcontroller +which initializes the card to match the EEPROM settings when the machine +is powered on. These cards actually behave just like they have jumpers +for all of the settings. Configure driver for MSS, MPU, SB/SB Pro and OPL3 +supports with these cards. + +There are some new Sound Galaxies in the market. I have no experience with +them so read the card's manual carefully. + +ESS ES1688 and ES688 'AudioDrive' based cards +--------------------------------------------- + +Support for these two ESS chips is embedded in the SB driver. +Configure these cards just like SB. Enable the 'SB MPU401 MIDI port' +if you want to use MIDI features of ES1688. ES688 doesn't have MPU mode +so you don't need to enable it (the driver uses normal SB MIDI automatically +with ES688). + +NOTE! ESS cards are not compatible with MSS/WSS so don't worry if MSS support +of OSS doesn't work with it. + +There are some ES1688/688 based sound cards and (particularly) motherboards +which use software configurable I/O port relocation feature of the chip. +This ESS proprietary feature is supported only by OSS/Linux. + +There are ES1688 based cards which use different interrupt pin assignment than +recommended by ESS (5, 7, 9/2 and 10). In this case all IRQs don't work. +At least a card called (Pearl?) Hypersound 16 supports IRQ 15 but it doesn't +work. + +ES1868 is a PnP chip which is (supposed to be) compatible with ESS1688 +probably works with OSS/Free after initialization using isapnptools. + +Reveal cards +------------ + +There are several different cards made/marketed by Reveal. Some of them +are compatible with SoundScape and some use the MAD16 chip. You may have +to look at the card and try to identify its origin. + +Diamond +------- + +The oldest (Sierra Aria based) sound cards made by Diamond are not supported +(they may work if the card is initialized using DOS). The recent (LX?) +models are based on the MAD16 chip which is supported by the driver. + +Audio Excel DSP16 +----------------- + +Support for this card is currently not functional. A new driver for it +should be available later this year. + +PCMCIA cards +------------ + +Sorry, can't help. Some cards may work and some don't. + +TI TM4000M notebooks +-------------------- + +These computers have a built in sound support based on the Jazz chipset. +Look at the instructions for MV Jazz (above). It's also important to note +that there is something wrong with the mouse port and sound at least on +some TM models. Don't enable the "C&T 82C710 mouse port support" when +configuring Linux. Having it enabled is likely to cause mysterious problems +and kernel failures when sound is used. + +miroSOUND +--------- + +The miroSOUND PCM1-pro, PCM12 and PCM20 radio has been used +successfully. These cards are based on the MAD16, OPL4, and CS4231A chips +and everything said in the section about MAD16 cards applies here, +too. The only major difference between the PCMxx and other MAD16 cards +is that instead of the mixer in the CS4231 codec a separate mixer +controlled by an on-board 80C32 microcontroller is used. Control of +the mixer takes place via the ACI (miro's audio control interface) +protocol that is implemented in a separate lowlevel driver. Make sure +you compile this ACI driver together with the normal MAD16 support +when you use a miroSOUND PCMxx card. The ACI mixer is controlled by +/dev/mixer and the CS4231 mixer by /dev/mixer1 (depends on load +time). Only in special cases you want to change something regularly on +the CS4231 mixer. + +The miroSOUND PCM12 and PCM20 radio is capable of full duplex +operation (simultaneous PCM replay and recording), which allows you to +implement nice real-time signal processing audio effect software and +network telephones. The ACI mixer has to be switched into the "solo" +mode for duplex operation in order to avoid feedback caused by the +mixer (input hears output signal). You can de-/activate this mode +through toggleing the record button for the wave controller with an +OSS-mixer. + +The PCM20 contains a radio tuner, which is also controlled by +ACI. This radio tuner is supported by the ACI driver together with the +miropcm20.o module. Also the 7-band equalizer is integrated +(limited by the OSS-design). Developement has started and maybe +finished for the RDS decoder on this card, too. You will be able to +read RadioText, the Programme Service name, Programme TYpe and +others. Even the v4l radio module benefits from it with a refined +strength value. See aci.[ch] and miropcm20*.[ch] for more details. + +The following configuration parameters have worked fine for the PCM12 +in Markus Kuhn's system, many other configurations might work, too: +CONFIG_MAD16_BASE=0x530, CONFIG_MAD16_IRQ=11, CONFIG_MAD16_DMA=3, +CONFIG_MAD16_DMA2=0, CONFIG_MAD16_MPU_BASE=0x330, CONFIG_MAD16_MPU_IRQ=10, +DSP_BUFFSIZE=65536, SELECTED_SOUND_OPTIONS=0x00281000. + +Bas van der Linden is using his PCM1-pro with a configuration that +differs in: CONFIG_MAD16_IRQ=7, CONFIG_MAD16_DMA=1, CONFIG_MAD16_MPU_IRQ=9 + +Compaq Deskpro XL +----------------- + +The builtin sound hardware of Compaq Deskpro XL is now supported. +You need to configure the driver with MSS and OPL3 supports enabled. +In addition you need to manually edit linux/drivers/sound/local.h and +to add a line containing "#define DESKPROXL" if you used +make menuconfig/xconfig. + +Others? +------- + +Since there are so many different sound cards, it's likely that I have +forgotten to mention many of them. Please inform me if you know yet another +card which works with Linux, please inform me (or is anybody else +willing to maintain a database of supported cards (just like in XF86)?). + +Cards not supported yet +======================= + +Please check the version of sound driver you are using before +complaining that your card is not supported. It's possible you are +using a driver version which was released months before your card was +introduced. + +First of all, there is an easy way to make most sound cards work with Linux. +Just use the DOS based driver to initialize the card to a known state, then use +loadlin.exe to boot Linux. If Linux is configured to use the same I/O, IRQ and +DMA numbers as DOS, the card could work. +(ctrl-alt-del can be used in place of loadlin.exe but it doesn't work with +new motherboards). This method works also with all/most PnP sound cards. + +Don't get fooled with SB compatibility. Most cards are compatible with +SB but that may require a TSR which is not possible with Linux. If +the card is compatible with MSS, it's a better choice. Some cards +don't work in the SB and MSS modes at the same time. + +Then there are cards which are no longer manufactured and/or which +are relatively rarely used (such as the 8 bit ProAudioSpectrum +models). It's extremely unlikely that such cards ever get supported. +Adding support for a new card requires much work and increases time +required in maintaining the driver (some changes need to be done +to all low level drivers and be tested too, maybe with multiple +operating systems). For this reason I have made a decision to not support +obsolete cards. It's possible that someone else makes a separately +distributed driver (diffs) for the card. + +Writing a driver for a new card is not possible if there are no +programming information available about the card. If you don't +find your new card from this file, look from the home page +(http://www.opensound.com/ossfree). Then please contact +manufacturer of the card and ask if they have (or are willing to) +released technical details of the card. Do this before contacting me. I +can only answer 'no' if there are no programming information available. + +I have made decision to not accept code based on reverse engineering +to the driver. There are three main reasons: First I don't want to break +relationships to sound card manufacturers. The second reason is that +maintaining and supporting a driver without any specs will be a pain. +The third reason is that companies have freedom to refuse selling their +products to other than Windows users. + +Some companies don't give low level technical information about their +products to public or at least their require signing a NDA. It's not +possible to implement a freeware driver for them. However it's possible +that support for such cards become available in the commercial version +of this driver (see http://www.4Front-tech.com/oss.html for more info). + +There are some common audio chipsets that are not supported yet. For example +Sierra Aria and IBM Mwave. It's possible that these architectures +get some support in future but I can't make any promises. Just look +at the home page (http://www.opensound.com/ossfree/new_cards.html) +for latest info. + +Information about unsupported sound cards and chipsets is welcome as well +as free copies of sound cards, SDKs and operating systems. + +If you have any corrections and/or comments, please contact me. + +Hannu Savolainen +hannu@opensound.com + +Personal home page: http://www.compusonic.fi/~hannu +home page of OSS/Free: http://www.opensound.com/ossfree + +home page of commercial OSS +(Open Sound System) drivers: http://www.opensound.com/oss.html diff --git a/Documentation/sound/oss/README.awe b/Documentation/sound/oss/README.awe new file mode 100644 index 0000000..80054cd --- /dev/null +++ b/Documentation/sound/oss/README.awe @@ -0,0 +1,218 @@ +================================================================ + AWE32 Sound Driver for Linux / FreeBSD + version 0.4.3; Nov. 1, 1998 + + Takashi Iwai <iwai@ww.uni-erlangen.de> +================================================================ + +* GENERAL NOTES + +This is a sound driver extension for SoundBlaster AWE32 and other +compatible cards (AWE32-PnP, SB32, SB32-PnP, AWE64 & etc) to enable +the wave synth operations. The driver is provided for Linux 1.2.x +and 2.[012].x kernels, as well as FreeBSD, on Intel x86 and DEC +Alpha systems. + +This driver was written by Takashi Iwai <iwai@ww.uni-erlangen.de>, +and provided "as is".

The precise installation procedure is described in the +AWE64-Mini-HOWTO and linux-kernel/Documetation/sound/AWE32. + +If you're using PnP cards, the card must be initialized before loading +the sound driver. There're several options to do this: + - Initialize the card via ISA PnP tools, and load the sound module. + - Initialize the card on DOS, and load linux by loadlin.exe + - Use PnP kernel driver (for Linux-2.x.x) +The detailed instruction for the solution using isapnp tools is found +in many documents like above. A brief instruction is also included in +the installation document of this package. +For PnP driver project, please refer to the following URL: + http://www-jcr.lmh.ox.ac.uk/~pnp/ + + +* USING THE DRIVER + +The awedrv has several different playing modes to realize easy channel +allocation for MIDI songs. To hear the exact sound quality, you need +to obtain the extended sequencer program, drvmidi or playmidi-2.5. + +For playing MIDI files, you *MUST* load the soundfont file on the +driver previously by sfxload utility. Otherwise you'll here no sounds +at all! All the utilities and driver source packages are found in the +above URL. The sfxload program is included in the package +awesfx-0.4.3.tgz. Binary packages are available there, too. See the +instruction in each package for installation. + +Loading a soundfont file is very simple. Just execute the command + + % sfxload synthgm.sbk + +Then, sfxload transfers the file "synthgm.sbk" to the driver. +Both SF1 and SF2 formats are accepted. + +Now you can hear midi musics by a midi player. + + % drvmidi foo.mid + +If you run MIDI player after MOD player, you need to load soundfont +files again, since MOD player programs clear the previous loaded +samples by their own data. + +If you have only 512kb on the sound card, I recommend to use dynamic +sample loading via -L option of drvmidi. 2MB GM/GS soundfont file is +available in most midi files. + + % sfxload synthgm + % drvmidi -L 2mbgmgs foo.mid + +This makes a big difference (believe me)! For more details, please +refer to the FAQ list which is available on the URL above. + +The current chorus, reverb and equalizer status can be changed by +aweset utility program (included in awesfx package). Note that +some awedrv-native programs (like drvmidi and xmp) will change the +current settings by themselves. The aweset program is effective +only for other programs like playmidi. + +Enjoy. + + +* COMPILE FLAGS + +Compile conditions are defined in awe_config.h. + +[Compatibility Conditions] +The following flags are defined automatically when using installation +shell script. + +- AWE_MODULE_SUPPORT + indicates your Linux kernel supports module for each sound card + (in recent 2.1 or 2.2 kernels and unofficial patched 2.0 kernels + as distributed in the RH5.0 package). + This flag is automatically set when you're using 2.1.x kernels. + You can pass the base address and memory size via the following + module options, + io = base I/O port address (eg. 0x620) + memsize = DRAM size in kilobytes (eg. 512) + As default, AWE driver probes these values automatically. + + +[Hardware Conditions] +You DON'T have to define the following two values. +Define them only when the driver couldn't detect the card properly. + +- AWE_DEFAULT_BASE_ADDR (default: not defined) + specifies the base port address of your AWE32 card. + 0 means to autodetect the address. + +- AWE_DEFAULT_MEM_SIZE (default: not defined) + specifies the memory size of your AWE32 card in kilobytes. + -1 means to autodetect its size. + + +[Sample Table Size] +From ver.0.4.0, sample tables are allocated dynamically (except +Linux-1.2.x system), so you need NOT to touch these parameters. +Linux-1.2.x users may need to increase these values to appropriate size +if the sound card is equipped with more DRAM. + +- AWE_MAX_SF_LISTS, AWE_MAX_SAMPLES, AWE_MAX_INFOS + + +[Other Conditions] + +- AWE_ALWAYS_INIT_FM (default: not defined) + indicates the AWE driver always initialize FM passthrough even + without DRAM on board.

As the help for them says, set them unless you know your +card does not use one of these chips for FM support. + + Once you are configured, make zlilo, modules, modules_install; reboot. +Note that it is no longer necessary or possible to configure sound in the +drivers/sound dir. Now one simply configures and makes one's kernel and +modules in the usual way. + + Then, add to your /etc/modprobe.conf something like: + +alias char-major-14-* sb +install sb /sbin/modprobe -i sb && /sbin/modprobe adlib_card +options sb io=0x220 irq=7 dma=1 dma16=5 mpu_io=0x330 +options adlib_card io=0x388 # FM synthesizer + + Alternatively, if you have compiled in kernel level ISAPnP support: + +alias char-major-14 sb +post-install sb /sbin/modprobe "-k" "adlib_card" +options adlib_card io=0x388 + + The effect of this is that the sound driver and all necessary bits and +pieces autoload on demand, assuming you use kerneld (a sound choice) and +autoclean when not in use. Also, options for the device drivers are +set. They will not work without them. Change as appropriate for your card. +If you are not yet using the very cool kerneld, you will have to "modprobe +-k sb" yourself to get things going. Eventually things may be fixed so +that this kludgery is not necessary; for the time being, it seems to work +well. + + Replace 'sb' with the driver for your card, and give it the right +options. To find the filename of the driver, look in +/lib/modules/<kernel-version>/misc. Mine looks like: + +adlib_card.o # This is the generic OPLx driver +opl3.o # The OPL3 driver +sb.o # <<The SoundBlaster driver. Yours may differ.>> +sound.o # The sound driver +uart401.o # Used by sb, maybe other cards + + Whichever card you have, try feeding it the options that would be the +default if you were making the driver wired, not as modules. You can +look at function referred to by module_init() for the card to see what +args are expected. + + Note that at present there is no way to configure the io, irq and other +parameters for the modular drivers as one does for the wired drivers.. One +needs to pass the modules the necessary parameters as arguments, either +with /etc/modprobe.conf or with command-line args to modprobe, e.g. + +modprobe sb io=0x220 irq=7 dma=1 dma16=5 mpu_io=0x330 +modprobe adlib_card io=0x388 + + recommend using /etc/modprobe.conf. + +Persistent DMA Buffers: + +The sound modules normally allocate DMA buffers during open() and +deallocate them during close(). Linux can often have problems allocating +DMA buffers for ISA cards on machines with more than 16MB RAM. This is +because ISA DMA buffers must exist below the 16MB boundary and it is quite +possible that we can't find a large enough free block in this region after +the machine has been running for any amount of time. The way to avoid this +problem is to allocate the DMA buffers during module load and deallocate +them when the module is unloaded. For this to be effective we need to load +the sound modules right after the kernel boots, either manually or by an +init script, and keep them around until we shut down. This is a little +wasteful of RAM, but it guarantees that sound always works. + +To make the sound driver use persistent DMA buffers we need to pass the +sound.o module a "dmabuf=1" command-line argument. This is normally done +in /etc/modprobe.conf like so: + +options sound dmabuf=1 + +If you have 16MB or less RAM or a PCI sound card, this is wasteful and +unnecessary. It is possible that machine with 16MB or less RAM will find +this option useful, but if your machine is so memory-starved that it +cannot find a 64K block free, you will be wasting even more RAM by keeping +the sound modules loaded and the DMA buffers allocated when they are not +needed. The proper solution is to upgrade your RAM. But you do also have +this improper solution as well. Use it wisely. + + I'm afraid I know nothing about anything but my setup, being more of a +text-mode guy anyway.

The official name in the documentation is CMI8330, SoundPro +is the nickname and the big inscription on the chip itself. + +The chip emulates a WSS as well as a SB16, but it has certain differences +in the mixer section which require separate support. It also emulates an +MPU401 and an OPL3 synthesizer, so you probably want to enable support +for these, too. + +The chip identifies itself as an AD1848, but its mixer is significantly +more advanced than the original AD1848 one. If your system works with +either WSS or SB16 and you are having problems with some mixer controls +(no CD audio, no line-in, etc), you might want to give this driver a try. +Detection should work, but it hasn't been widely tested, so it might still +mis-identify the chip. You can still force soundpro=1 in the modprobe +parameters for ad1848. Please let me know if it happens to you, so I can +adjust the detection routine. + +The chip is capable of doing full-duplex, but since the driver sees it as an +AD1848, it cannot take advantage of this. Moreover, the full-duplex mode is +not achievable through the WSS interface, b/c it needs a dma16 line which is +assigned only to the SB16 subdevice (with isapnp). Windows documentation +says the user must use WSS Playback and SB16 Recording for full-duplex, so +it might be possible to do the same thing under Linux. You can try loading +up both ad1848 and sb then use one for playback and the other for +recording. I don't know if this works, b/c I haven't tested it. Anyway, if +you try it, be very careful: the SB16 mixer *mostly* works, but certain +settings can have unexpected effects. Use the WSS mixer for best results. + +There is also a PCI SoundPro chip. I have not seen this chip, so I have +no idea if the driver will work with it. I suspect it won't. + +As with PnP cards, some configuration is required. There are two ways +of doing this. The most common is to use the isapnptools package to +initialize the card, and use the kernel module form of the sound +subsystem and sound drivers. Alternatively, some BIOS's allow manual +configuration of installed PnP devices in a BIOS menu, which should +allow using the non-modular sound drivers, i.e. built into the kernel. +Since in this latter case you cannot use module parameters, you will +have to enable support for the SoundPro at compile time. + +The IRQ and DMA values can be any that are considered acceptable for a +WSS. Assuming you've got isapnp all happy, then you should be able to +do something like the following (which *must* match the isapnp/BIOS +configuration): + +modprobe ad1848 io=0x530 irq=11 dma=0 soundpro=1 +-and maybe- +modprobe sb io=0x220 irq=5 dma=1 dma16=5 + +-then- +modprobe mpu401 io=0x330 irq=9 +modprobe opl3 io=0x388 + +If all goes well and you see no error messages, you should be able to +start using the sound capabilities of your system. If you get an +error message while trying to insert the module(s), then make +sure that the values of the various arguments match what you specified +in your isapnp configuration file, and that there is no conflict with +another device for an I/O port or interrupt. Checking the contents of +/proc/ioports and /proc/interrupts can be useful to see if you're +butting heads with another device. + +If you do not see the chipset version message, and none of the other +messages present in the system log are helpful, try adding 'debug=1' +to the ad1848 parameters, email me the syslog results and I'll do +my best to help. + +Lastly, if you're using modules and want to set up automatic module +loading with kmod, the kernel module loader, here is the section I +currently use in my conf.modules file: + +# Sound +post-install sound modprobe -k ad1848; modprobe -k mpu401; modprobe -k opl3 +options ad1848 io=0x530 irq=11 dma=0 +options sb io=0x220 irq=5 dma=1 dma16=5 +options mpu401 io=0x330 irq=9 +options opl3 io=0x388 + +The above ensures that ad1848 will be loaded whenever the sound system +is being used. + +Good luck. + +Ion + +NOT REALLY TESTED: +- recording +- recording device selection +- full-duplex + +TODO: +- implement mixer support for surround, loud, digital CD switches. +- come up with a scheme which allows recording volumes for each subdevice. +This is a major OSS API change. diff --git a/Documentation/sound/oss/Soundblaster b/Documentation/sound/oss/Soundblaster new file mode 100644 index 0000000..b288d46 --- /dev/null +++ b/Documentation/sound/oss/Soundblaster @@ -0,0 +1,53 @@ +modprobe sound +insmod uart401 +insmod sb ... + +This loads the driver for the Sound Blaster and assorted clones.

OSS/Free Driver for WaveFront soundcards + (Turtle Beach Maui, Tropez, Tropez Plus) + + Paul Barton-Davis, July 1998 + + VERSION 0.2.5 + +Driver Status +------------- + +Requires: Kernel 2.1.106 or later (the driver is included with kernels +2.1.109 and above) + +As of 7/22/1998, this driver is currently in *BETA* state. This means +that it compiles and runs, and that I use it on my system (Linux +2.1.106) with some reasonably demanding applications and uses. I +believe the code is approaching an initial "finished" state that +provides bug-free support for the Tropez Plus. + +Please note that to date, the driver has ONLY been tested on a Tropez +Plus. I would very much like to hear (and help out) people with Tropez +and Maui cards, since I think the driver can support those cards as +well. + +Finally, the driver has not been tested (or even compiled) as a static +(non-modular) part of the kernel. Alan Cox's good work in modularizing +OSS/Free for Linux makes this rather unnecessary. + +Some Questions +-------------- + +********************************************************************** +0) What does this driver do that the maui driver did not ? +********************************************************************** + +* can fully initialize a WaveFront card from cold boot - no DOS + utilities needed +* working patch/sample/program loading and unloading (the maui + driver didn't document how to make this work, and assumed + user-level preparation of the patch data for writing + to the board. ick.) +* full user-level access to all WaveFront commands +* for the Tropez Plus, (primitive) control of the YSS225 FX processor +* Virtual MIDI mode supported - 2 MIDI devices accessible via the + WaveFront's MPU401/UART emulation. One + accesses the WaveFront synth, the other accesses the + external MIDI connector. Full MIDI read/write semantics + for both devices. +* OSS-compliant /dev/sequencer interface for the WaveFront synth, + including native and GUS-format patch downloading. +* semi-intelligent patch management (prototypical at this point) + +********************************************************************** +1) What to do about MIDI interfaces ? +********************************************************************** + +The Tropez Plus (and perhaps other WF cards) can in theory support up +to 2 physical MIDI interfaces. One of these is connected to the +ICS2115 chip (the WaveFront synth itself) and is controlled by +MPU/UART-401 emulation code running as part of the WaveFront OS. The +other is controlled by the CS4232 chip present on the board. However, +physical access to the CS4232 connector is difficult, and it is +unlikely (though not impossible) that you will want to use it. + +An older version of this driver introduced an additional kernel config +variable which controlled whether or not the CS4232 MIDI interface was +configured. Because of Alan Cox's work on modularizing the sound +drivers, and now backporting them to 2.0.34 kernels, there seems to be +little reason to support "static" configuration variables, and so this +has been abandoned in favor of *only* module parameters. Specifying +"mpuio" and "mpuirq" for the cs4232 parameter will result in the +CS4232 MIDI interface being configured; leaving them unspecified will +leave it unconfigured (and thus unusable). + +BTW, I have heard from one Tropez+ user that the CS4232 interface is +more reliable than the ICS2115 one. I have had no problems with the +latter, and I don't have the right cable to test the former one +out.

However, if you have a WaveFront card, then you +almost certainly have the firmware, and if not, its freely available +on their website, at: + + http://www.tbeach.com/tbs/downloads/scardsdown.htm#tropezplus + +The file is called WFOS2001.MOT (for the Tropez+). + +This driver, however, doesn't use the pure firmware as distributed, +but instead relies on a somewhat processed form of it. You can +generate this very easily. Following an idea from Andrew Veliath's +Pinnacle driver, the following flex program will generate the +processed version: + +---- cut here ------------------------- +%option main +%% +^S[28].*\r$ printf ("%c%.*s", yyleng-1,yyleng-1,yytext); +<<EOF>> { fputc ('\0', stdout); return; } +\n {} +. {} +---- cut here ------------------------- + +To use it, put the above in file (say, ws.l) compile it like this: + + shell> flex -ows.c ws.l + shell> cc -o ws ws.c + +and then use it like this: + + ws < my-copy-of-the-oswf.mot-file > /etc/sound/wavefront.os + +If you put it somewhere else, you'll always have to use the wf_ospath +module parameter (see below) or alter the source code. + +********************************************************************** +7) How do I get it working ? +********************************************************************** + +Optionally, you can reboot with the "new" kernel (even though the only +changes have really been made to a module). + +Then, as root do: + + modprobe wavefront + +You should get something like this in /var/log/messages: + + WaveFront: firmware 1.20 already loaded. + +or + + WaveFront: no response to firmware probe, assume raw. + +then: + + WaveFront: waiting for memory configuration ... + WaveFront: hardware version 1.64 + WaveFront: available DRAM 8191k + WaveFront: 332 samples used (266 real, 13 aliases, 53 multi), 180 empty + WaveFront: 128 programs slots in use + WaveFront: 256 patch slots filled, 142 in use + +The whole process takes about 16 seconds, the longest waits being +after reporting the hardware version (during the firmware download), +and after reporting program status (during patch status inquiry). Its +shorter (about 10 secs) if the firmware is already loaded (i.e. only +warm reboots since the last firmware load). + +The "available DRAM" line will vary depending on how much added RAM +your card has. Mine has 8MB. + +To check basically functionality, use play(1) or splay(1) to send a +.WAV or other audio file through the audio portion. Then use playmidi +to play a General MIDI file. Try the "-D 0" to hear the +difference between sending MIDI to the WaveFront and using the OPL/3, +which is the default (I think ...). If you have an external synth(s) +hooked to the soundcard, you can use "-e" to route to the +external synth(s) (in theory, -D 1 should work as well, but I think +there is a bug in playmidi which prevents this from doing what it +should). + +********************************************************************** +8) What are the module parameters ? +********************************************************************** + +Its best to read wavefront.c for this, but here is a summary: + +integers: + wf_raw - if set, ignore apparent presence of firmware + loaded onto the ICS2115, reset the whole + board, and initialize it from scratch. (default = 0) + + fx_raw - if set, always initialize the YSS225 processor + on the Tropez plus. (default = 1) + + < The next 4 are basically for kernel hackers to allow + tweaking the driver for testing purposes. > + + wait_usecs - loop timer used when waiting for + status conditions on the board. + The default is 150. + + debug_default - debugging flags. See sound/wavefront.h + for WF_DEBUG_* values. Default is zero. + Setting this allows you to debug the + driver during module installation. +strings: + ospath - path to get to the pre-processed OS firmware. + (default: /etc/sound/wavefront.os) + +********************************************************************** +9) Who should I contact if I have problems? +********************************************************************** + +Just me: Paul Barton-Davis <pbd@op.net> + + diff --git a/Documentation/sound/oss/btaudio b/Documentation/sound/oss/btaudio new file mode 100644 index 0000000..1a693e6 --- /dev/null +++ b/Documentation/sound/oss/btaudio @@ -0,0 +1,92 @@ + +Intro +===== + +people start bugging me about this with questions, looks like I +should write up some documentation for this beast.

All rights reserved. + + +At the time of this writing, March 1999, there are two models of +Visual Workstation, the 320 and the 540. This document only describes +those models. Future Visual Workstation models may have different +sound capabilities, and this driver will probably not work on those +boxes. + +The Visual Workstation has an Analog Devices AD1843 "SoundComm" audio +codec chip. The AD1843 is accessed through the Cobalt I/O ASIC, also +known as Lithium. This driver programs both both chips. + +============================================================================== +QUICK CONFIGURATION + + # insmod soundcore + # insmod vwsnd + +============================================================================== +I/O CONNECTIONS + +On the Visual Workstation, only three of the AD1843 inputs are hooked +up. The analog line in jacks are connected to the AD1843's AUX1 +input. The CD audio lines are connected to the AD1843's AUX2 input. +The microphone jack is connected to the AD1843's MIC input. The mic +jack is mono, but the signal is delivered to both the left and right +MIC inputs. You can record in stereo from the mic input, but you will +get the same signal on both channels (within the limits of A/D +accuracy). Full scale on the Line input is +/- 2.0 V. Full scale on +the MIC input is 20 dB less, or +/- 0.2 V. + +The AD1843's LOUT1 outputs are connected to the Line Out jacks. The +AD1843's HPOUT outputs are connected to the speaker/headphone jack. +LOUT2 is not connected. Line out's maximum level is +/- 2.0 V peak to +peak. The speaker/headphone out's maximum is +/- 4.0 V peak to peak. + +The AD1843's PCM input channel and one of its output channels (DAC1) +are connected to Lithium. The other output channel (DAC2) is not +connected. + +============================================================================== +CAPABILITIES + +The AD1843 has PCM input and output (Pulse Code Modulation, also known +as wavetable). PCM input and output can be mono or stereo in any of +four formats. The formats are 16 bit signed and 8 bit unsigned, +u-Law, and A-Law format. Any sample rate from 4 KHz to 49 KHz is +available, in 1 Hz increments. + +The AD1843 includes an analog mixer that can mix all three input +signals (line, mic and CD) into the analog outputs. The mixer has a +separate gain control and mute switch for each input. + +There are two outputs, line out and speaker/headphone out. They +always produce the same signal, and the speaker always has 3 dB more +gain than the line out. The speaker/headphone output can be muted, +but this driver does not export that function. + +The hardware can sync audio to the video clock, but this driver does +not have a way to specify syncing to video. + +============================================================================== +PROGRAMMING + +This section explains the API supported by the driver. Also see the +Open Sound Programming Guide at http://www.opensound.com/pguide/ . +This section assumes familiarity with that document. + +The driver has two interfaces, an I/O interface and a mixer interface. +There is no MIDI or sequencer capability. + +============================================================================== +PROGRAMMING PCM I/O + +The I/O interface is usually accessed as /dev/audio or /dev/dsp. +Using the standard Open Sound System (OSS) ioctl calls, the sample +rate, number of channels, and sample format may be set within the +limitations described above. The driver supports triggering. It also +supports getting the input and output pointers with one-sample +accuracy. + +The SNDCTL_DSP_GETCAP ioctl returns these capabilities. + + DSP_CAP_DUPLEX - driver supports full duplex. + + DSP_CAP_TRIGGER - driver supports triggering. + + DSP_CAP_REALTIME - values returned by SNDCTL_DSP_GETIPTR + and SNDCTL_DSP_GETOPTR are accurate to a few samples. + +Memory mapping (mmap) is not implemented. + +The driver permits subdivided fragment sizes from 64 to 4096 bytes. +The number of fragments can be anything from 3 fragments to however +many fragments fit into 124 kilobytes. It is up to the user to +determine how few/small fragments can be used without introducing +glitches with a given workload. Linux is not realtime, so we can't +promise anything. (sigh...) + +When this driver is switched into or out of mu-Law or A-Law mode on +output, it may produce an audible click. This is unavoidable. To +prevent clicking, use signed 16-bit mode instead, and convert from +mu-Law or A-Law format in software. + +============================================================================== +PROGRAMMING THE MIXER INTERFACE + +The mixer interface is usually accessed as /dev/mixer. It is accessed +through ioctls. The mixer allows the application to control gain or +mute several audio signal paths, and also allows selection of the +recording source. + +Each of the constants described here can be read using the +MIXER_READ(SOUND_MIXER_xxx) ioctl. Those that are not read-only can +also be written using the MIXER_WRITE(SOUND_MIXER_xxx) ioctl. In most +cases, <sys/soundcard.h> defines constants SOUND_MIXER_READ_xxx and +SOUND_MIXER_WRITE_xxx which work just as well. + +SOUND_MIXER_CAPS Read-only + +This is a mask of optional driver capabilities that are implemented. +This driver's only capability is SOUND_CAP_EXCL_INPUT, which means +that only one recording source can be active at a time. + +SOUND_MIXER_DEVMASK Read-only + +This is a mask of the sound channels. This driver's channels are PCM, +LINE, MIC, CD, and RECLEV. + +SOUND_MIXER_STEREODEVS Read-only + +This is a mask of which sound channels are capable of stereo. All +channels are capable of stereo. (But see caveat on MIC input in I/O +CONNECTIONS section above). + +SOUND_MIXER_OUTMASK Read-only + +This is a mask of channels that route inputs through to outputs. +Those are LINE, MIC, and CD. + +SOUND_MIXER_RECMASK Read-only + +This is a mask of channels that can be recording sources. Those are +PCM, LINE, MIC, CD. + +SOUND_MIXER_PCM Default: 0x5757 (0 dB) + +This is the gain control for PCM output. The left and right channel +gain are controlled independently. This gain control has 64 levels, +which range from -82.5 dB to +12.0 dB in 1.5 dB steps. Those 64 +levels are mapped onto 100 levels at the ioctl, see below. + +SOUND_MIXER_LINE Default: 0x4a4a (0 dB) + +This is the gain control for mixing the Line In source into the +outputs. The left and right channel gain are controlled +independently. This gain control has 32 levels, which range from +-34.5 dB to +12.0 dB in 1.5 dB steps. Those 32 levels are mapped onto +100 levels at the ioctl, see below. + +SOUND_MIXER_MIC Default: 0x4a4a (0 dB) + +This is the gain control for mixing the MIC source into the outputs. +The left and right channel gain are controlled independently. This +gain control has 32 levels, which range from -34.5 dB to +12.0 dB in +1.5 dB steps. Those 32 levels are mapped onto 100 levels at the +ioctl, see below. + +SOUND_MIXER_CD Default: 0x4a4a (0 dB) + +This is the gain control for mixing the CD audio source into the +outputs. The left and right channel gain are controlled +independently. This gain control has 32 levels, which range from +-34.5 dB to +12.0 dB in 1.5 dB steps. Those 32 levels are mapped onto +100 levels at the ioctl, see below. + +SOUND_MIXER_RECLEV Default: 0 (0 dB) + +This is the gain control for PCM input (RECording LEVel). The left +and right channel gain are controlled independently. This gain +control has 16 levels, which range from 0 dB to +22.5 dB in 1.5 dB +steps. Those 16 levels are mapped onto 100 levels at the ioctl, see +below. + +SOUND_MIXER_RECSRC Default: SOUND_MASK_LINE + +This is a mask of currently selected PCM input sources (RECording +SouRCes). Because the AD1843 can only have a single recording source +at a time, only one bit at a time can be set in this mask. The +allowable values are SOUND_MASK_PCM, SOUND_MASK_LINE, SOUND_MASK_MIC, +or SOUND_MASK_CD. Selecting SOUND_MASK_PCM sets up internal +resampling which is useful for loopback testing and for hardware +sample rate conversion. But software sample rate conversion is +probably faster, so I don't know how useful that is. + +SOUND_MIXER_OUTSRC DEFAULT: SOUND_MASK_LINE|SOUND_MASK_MIC|SOUND_MASK_CD + +This is a mask of sources that are currently passed through to the +outputs. Those sources whose bits are not set are muted. + +============================================================================== +GAIN CONTROL + +There are five gain controls listed above. Each has 16, 32, or 64 +steps. Each control has 1.5 dB of gain per step. Each control is +stereo. + +The OSS defines the argument to a channel gain ioctl as having two +components, left and right, each of which ranges from 0 to 100. The +two components are packed into the same word, with the left side gain +in the least significant byte, and the right side gain in the second +least significant byte. In C, we would say this. + + #include <assert.h> + + ... + + assert(leftgain >= 0 && leftgain <= 100); + assert(rightgain >= 0 && rightgain <= 100); + arg = leftgain | rightgain << 8; + +So each OSS gain control has 101 steps. But the hardware has 16, 32, +or 64 steps. The hardware steps are spread across the 101 OSS steps +nearly evenly. The conversion formulas are like this, given N equals +16, 32, or 64. + + int round = N/2 - 1; + OSS_gain_steps = (hw_gain_steps * 100 + round) / (N - 1); + hw_gain_steps = (OSS_gain_steps * (N - 1) + round) / 100; + +Here is a snippet of C code that will return the left and right gain +of any channel in dB. Pass it one of the predefined gain_desc_t +structures to access any of the five channels' gains. + + typedef struct gain_desc { + float min_gain; + float gain_step; + int nbits; + int chan; + } gain_desc_t; + + const gain_desc_t gain_pcm = { -82.5, 1.5, 6, SOUND_MIXER_PCM }; + const gain_desc_t gain_line = { -34.5, 1.5, 5, SOUND_MIXER_LINE }; + const gain_desc_t gain_mic = { -34.5, 1.5, 5, SOUND_MIXER_MIC }; + const gain_desc_t gain_cd = { -34.5, 1.5, 5, SOUND_MIXER_CD }; + const gain_desc_t gain_reclev = { 0.0, 1.5, 4, SOUND_MIXER_RECLEV }; + + int get_gain_dB(int fd, const gain_desc_t *gp, + float *left, float *right) + { + int word; + int lg, rg; + int mask = (1 << gp->nbits) - 1; + + if (ioctl(fd, MIXER_READ(gp->chan), &word) != 0) + return -1; /* fail */ + lg = word & 0xFF; + rg = word >> 8 & 0xFF; + lg = (lg * mask + mask / 2) / 100; + rg = (rg * mask + mask / 2) / 100; + *left = gp->min_gain + gp->gain_step * lg; + *right = gp->min_gain + gp->gain_step * rg; + return 0; + } + +And here is the corresponding routine to set a channel's gain in dB. + + int set_gain_dB(int fd, const gain_desc_t *gp, float left, float right) + { + float max_gain = + gp->min_gain + (1 << gp->nbits) * gp->gain_step; + float round = gp->gain_step / 2; + int mask = (1 << gp->nbits) - 1; + int word; + int lg, rg; + + if (left < gp->min_gain || right < gp->min_gain) + return EINVAL; + lg = (left - gp->min_gain + round) / gp->gain_step; + rg = (right - gp->min_gain + round) / gp->gain_step; + if (lg >= (1 << gp->nbits) || rg >= (1 << gp->nbits)) + return EINVAL; + lg = (100 * lg + mask / 2) / mask; + rg = (100 * rg + mask / 2) / mask; + word = lg | rg << 8; + + return ioctl(fd, MIXER_WRITE(gp->chan), &word); + } + |
