Modified -configure to handle this. -- Removed initialization messages from the -modularized version. They can be enabled by using init_trace=1 in -the insmod command line (insmod sound init_trace=1). -- More AIX stuff. -- Added support for syncronizing dsp/audio devices with /dev/sequencer. -- mmap() support for dsp/audio devices. - -Since 3.5-alpha5 -- AIX port. -- Changed some xxx_PATCH macros in soundcard.h to work with - big endian machines. - -Since 3.5-alpha4 -- Removed the 'setfx' stuff from the version distributed with kernel - sources. - -Since 3.5-alpha3 -- Moved stuff from the 'setfx' program to the AudioTriX Pro driver. - -Since 3.5-alpha2 -- Modifications to makefile and configure.c. Unnecessary sources - are no longer compiled. Newly created local.h is also copied to - /etc/soundconf. "make oldconfig" reads /etc/soundconf and produces - new local.h which is compatible with current version of the driver. -- Some fixes to the SB16 support. -- Fixed random protection fault in gus_wave.c - -Since 3.5-alpha1 -- Modified to work with Linux-1.3.33 and leater -- Some minor changes - -Since 3.0.2 -- Support for CS4232 based PnP cards (AcerMagic S23 etc). -- Full duplex support for some CS4231, CS4232 and AD1845 based cards -(GUA MAX, AudioTrix Pro, AcerMagic S23 and many MAD16/Mozart cards -having a codec mentioned above). -- Almost fully rewritten loadable modules support. -- Fixed some bugs. -- Huge amount of testing (more testing is still required). -- mmap() support (works with some cards). Requires much more testing. -- Sample/patch/program loading for TB Maui/Tropez. No initialization -since TB doesn't allow me to release that code. -- Using CS4231 compatible codecs as timer for /dev/music. - -Since 3.0.1 -- Added allocation of I/O ports, DMA channels and interrupts -to the initialization code. This may break modules support since -the driver may not free some resources on unload. Should be fixed soon. - -Since 3.0 -- Some important bug fixes. -- select() for /dev/dsp and /dev/audio (Linux only). -(To use select() with read, you have to call read() to start -the recording. Calling write() kills recording immediately so -use select() carefully when you are writing a half duplex app. -Full duplex mode is not implemented yet.) Select works also with -/dev/sequencer and /dev/music. Maybe with /dev/midi## too. - -Since 3.0-beta2 -- Minor fixes. -- Added Readme.cards - -Since 3.0-beta1 -- Minor fixes to the modules support. -- Eliminated call to sb_free_irq() in ad1848.c -- Rewritten MAD16&Mozart support (not tested with MAD16 Pro). -- Fix to DMA initialization of PSS cards. -- Some fixes to ad1848/cs42xx mixer support (GUS MAX, MSS, etc.) -- Fixed some bugs in the PSS driver which caused I/O errors with - the MSS mode (/dev/dsp). - -Since 3.0-950506 -- Recording with GUS MAX fixed. It works when the driver is configured - to use two DMA channels with GUS MAX (16 bit ones recommended). - -Since 3.0-94xxxx -- Too many changes - -Since 3.0-940818 -- Fixes for Linux 1.1.4x. -- Disables Disney Sound System with SG NX Pro 16 (less noise). - -Since 2.90-2 -- Fixes to soundcard.h -- Non blocking mode to /dev/sequencer -- Experimental detection code for Ensoniq Soundscape. - -Since 2.90 -- Minor and major bug fixes - -Since pre-3.0-940712 -- GUS MAX support -- Partially working MSS/WSS support (could work with some cards). -- Hardware u-Law and A-Law support with AD1848/CS4248 and CS4231 codecs - (GUS MAX, GUS16, WSS etc). Hardware ADPCM is possible with GUS16 and - GUS MAX, but it doesn't work yet. -Since pre-3.0-940426 -- AD1848/CS4248/CS4231 codec support (MSS, GUS MAX, Aztec, Orchid etc). -This codec chip is used in various soundcards. This version is developed -for the 16 bit daughtercard of GUS. It should work with other cards also -if the following requirements are met: - - The I/O, IRQ and DMA settings are jumper selectable or - the card is initialized by booting DOS before booting Linux (etc.). - - You add the IO, IRQ and DMA settings manually to the local.h. - (Just define GUS16_BASE, GUS16_IRQ and GUS16_DMA).

Initial ALPHA TEST version (untested). - -Since 2.3b -- Fixed bug which made it impossible to make long recordings to disk. - Recording was not restarted after a buffer overflow situation. -- Limited mixer support for GUS. -- Numerous improvements to the GUS driver by Andrew Robinson. Including - some click removal etc. - -Since 2.3 -- Fixed some minor bugs in the SB16 driver. - -Since 2.2b -- Full SB16 DSP support. 8/16 bit, mono/stereo -- The SCO and FreeBSD versions should be in sync now. There are some - problems with SB16 and GUS in the freebsd versions. - The DMA buffer allocation of the SCO version has been polished but - there could still be some problems. At least it hogs memory. - The DMA channel - configuration method used in the sco/System is a hack. -- Support for the MPU emulation of the SB16. -- Some big arrays are now allocated boot time. This makes the bss segment - smaller which makes it possible to use the full driver with - NetBSD. These arrays are not allocated if no suitable soundcard is available. -- Fixed a bug in the compute_and_set_volume in gus_wave.c -- Fixed the too fast mono playback problem of SB Pro and PAS16. - -Since 2.2 -- Stereo recording for SB Pro. Somehow it was missing and nobody - had noticed it earlier. -- Minor polishing. -- Interpreting of boot time arguments (sound=) for Linux. -- Breakup of sb_dsp.c. Parts of the code has been moved to - sb_mixer.c and sb_midi.c - -Since 2.1 -- Preliminary support for SB16. - - The SB16 mixer is supported in its native mode. - - Digitized voice capability up to 44.1 kHz/8 bit/mono - (16 bit and stereo support coming in the next release). -- Fixed some bugs in the digitized voice driver for PAS16. -- Proper initialization of the SB emulation of latest PAS16 models. - -- Significantly improved /dev/dsp and /dev/audio support. - - Now supports half duplex mode. It's now possible to record and - playback without closing and reopening the device. - - It's possible to use smaller buffers than earlier. There is a new - ioctl(fd, SNDCTL_DSP_SUBDIVIDE, &n) where n should be 1, 2 or 4. - This call instructs the driver to use smaller buffers. The default - buffer size (0.5 to 1.0 seconds) is divided by n. Should be called - immediately after opening the device. - -Since 2.0 -Just cosmetic changes. diff --git a/sys/i386/isa/sound/COPYING b/sys/i386/isa/sound/COPYING deleted file mode 100644 index d1509c5..0000000 --- a/sys/i386/isa/sound/COPYING +++ /dev/null @@ -1,25 +0,0 @@ -/* - * Copyright by Hannu Savolainen 1993 - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.

The original Pro Audio Spectrum as well as the PAS+ are not - and will not be supported by VoxWare. - -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 - NOTE! The ASP chip and the EMU synth of the AWE32 is not supported - since their manufacturer doesn't release information about - the card. However both the AB16ASP and the AWE32 work with - VoxWare just like a SB16. Also see the comment about some - unsupported cards at the end of this file. - SB16 compatible cards by other manufacturers than Creative. - You have been fooled since there are no SB16 compatible - cards in the market (July95). 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 could also - be a proprietary one like MV Jazz16. - -Gravis Ultrasound (GUS) - GUS - GUS + the 16 bit option - GUS MAX - GUS ACE (No MIDI port and audio recording) - -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 soundcards are compatible with it. However - don't enable MPU401 mode blindly. Many cards having native support - in VoxWare have their own MPU401 driver. Enabling the standard one - will cause a conflict with these cards. So look if your card is - in the list of supported cards before enabling MPU401. - -Windows Sound System (MSS/WSS) - Even Microsoft has discontinued their own Sound System card, they - managed to make 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 soundcards are based on one of the MSS compatible codec - chip. 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 to VoxWare. Note also that most MSS compatible cards - require special boot time initialization which may not be present - in VoxWare. Also some MSS compatible cards have native support in - VoxWare. 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. - -6850 UART MIDI - This UART chip is used in the MIDI interface of some (rare) - soundcards. It's supported by VoxWare in case you need it. - -Yamaha FM synthesizers (OPL2, OPL3 and OPL4) - Most soundcards 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 which has a OPL3 and - a wave table synthesizer packed on the same chip. VoxWare supports - just the OPL3 mode directly. Most cards having a OPL4 (like - SM Wave and AudioTriX Pro) support the OPL4 mode using MPU401 - emulation. Writing a native OPL4 support to VoxWare 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. - -PSS based cards (AD1848 + ADSP-2115 + Echo ESC614 ASIC) - Analog Devices and Echo Speech have together defined a soundcard - 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. - - VoxWare supports downloading DSP algorithms to these cards. - -MediaTriX AudioTriX Pro - The ATP card is built around a CS4231 codec and a 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 soundcard 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. - -MAD16 and Mozart based cards - The Mozart (OAK OTI-601) and MAD16 Pro (OPTi 82C929) interface - chips are used in many different soundcards, including some - cards by Reveal and Turtle Beach (Tropez). Purpose of these - chips is to connect other audio components to the PC bus. The - interface chip performs address decoding for the other chips. - -Audio Excell DSP16 - Support for this card is made by Riccardo Faccetti - (riccardo@cdc8g5.cdc.polimi.it). See aedsp16.c for more info. - -Crystal CS4232 based cards such as AcerMagic S23 - 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). - -Turtle Beach Maui and Tropez - VoxWare supports sample, parch and program loading commands - described in the Maui/Tropez User's manual. There is no initialization - code for Maui so it must be initialized using DOS. Audio side of Tropez - is based on the MAD16 chip (see above). - -Jumpers and software configuration ----------------------------------- - -Some of the earliest soundcards were jumper configurable. You have to -configure VoxWare to configure VoxWare 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. - -VoxWare handles software configurable cards automaticly. 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). - -VoxWare sets the soft configurable parameters of the card automaticly -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 soundcards are based on some standard chips. If you -are lucky, all of them could be supported by VoxWare. 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 much more cards in the word than listed above. The first thing to -do with these cards is to check if they emulate some other card/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 a known I/O, IRQ and DMA -settings. If VoxWare is configured to use the same settings, everything should -work OK. - - -Configuring VoxWare (with Linux) -================================ - -VoxWare sound driver is currently a part of Linux kernel distribution. The -driver files are located in directory /usr/src/linux/drivers/sound. - -**************************************************************************** -* VoxWare MUST BE CONFIGURED AND COMPILED WITH THE KERNEL. TRYING * -* TO COMPILE IT ALONE WILL _NOT_ WORK. * -* * -* 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 to the question about Sound card support (after -questions about mouse, CD-ROM, ftape, etc. supports). Sound config options -will then be asked after some additional questions. - -After configuring the kernel and sound driver, run "make dep" and compile -the kernel following instructions in the kernel README. - -The sound driver configuration dialog -------------------------------------- - -All config information of the sound driver is written to file -linux/drivers/sound/local.h. You may save the old version is this file and -use it again in case you want to use the same config later. In this case -just answer n to each question made by the sound config program and put -the original local.h back before running "make dep". -Don't do this if the version number of the sound driver has changed. In this -case you have to enter the configuration information again. - -If you already have the sound driver installed, consult printout of -"cat /dev/sndstat" when configuring the driver again. It gives the I/O, -IRQ and DMA settings you have used earlier. - - -The sound config program (linux/drivers/sound/configure) 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 dependig on the earlier choices. It may also -select some options automaticly as well. - - "ProAudioSpectrum 16 support", - - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_, - ProAudio 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. - "SoundBlaster 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. - - 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 soundcard today. However some natively supported cards - have their own driver for MPU401. Enabling the MPU401 option with - these cards wil 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. - 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 VoxWare, consult - the card specific instructions later in this file. Some drivers - have their own MSS support and enabling this option wil cause a - conflict. - "Ensoniq Soundscape support", - - Answer 'y' if you have a soundcard based on the Ensoniq SoundScape - chipset. Suach cards are being manufactured at least by Ensoniq, - Spea and Reveal (note that Reveal makes other cards also). - "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 or 82C929) 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 (latest ones). - "SoundBlaster Pro support", - - Enable this option if your card is SB Pro or SB16. Enable it - also with any SB Pro clones. Answering 'n' saves some amount of - memory but 'y' is the safe alterative. - "SoundBlaster 16 support", - - Enable if you have a SB16 (including the AWE32). - "Audio Excel DSP 16 initialization support", - - Don't know much about this card. Look at aedsp16.c for more info. - -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. - - "/dev/dsp and /dev/audio supports (usually required)", - - Answering 'n' disables /dev/dsp and /dev/audio. Answer 'y'. - "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. In some cases this file -is written to a .h file by the config program and then included to the driver -during compile. - -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 VoxWare is recommended. Using -different values could cause some problems when switching between -different operating systems. - -SoundBlasters (the original ones by Creative) ---------------------------------------------- - -It's possible to configure these cards to use different I/O, IRQ and -DMA settings. Since the available 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. - -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 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 yoy 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 ------------------------------------ - -There are nothing special with these cards. Just don't enable any -other cards in case you don't have them also. The PAS16 has -a SB mode so the driver config program will prompt for the SB settings -do. Use I/O 0x220 and DMA1 for the SB mode. Ensure that you assign different -IRQ numbers for the SB and PAS16 modes. - -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. - -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. - - - -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 propably enable the OPL3 synth also since -most MSS compatible cards have it. However check that this is true -before enabling OPL3. - -VoxWare 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 sound/pss_test for more info (in the VoxWare-3.0.tar.gz) -package. - -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 -attemp to use the same IRQ or DMA channels twice. - -The SB mode of ATP is implemented so the the ATP driver just enables SB -in the proper address. The SB driver handles the rest. Yoy 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 ------------------- - -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). - -SoundScape driver uses the MSS compatible codec of the card. It's important -to note that /dev/dsp0 (/dev/dsp is linked to /dev/dsp0 by default) -doesn't work with SoundScape (yet). The 'ssinit' program needs /dev/dsp0 so -that's the reason why it's there. It's possible that 'primary' pcm channel -becomes supported later. Currently the card's firmware doesn't contain -support for it. - -With 3.0 of VoxWare you have to change your system to use /dev/dsp1 by default -so execute: cd /dev;rm dsp;ln -s dsp1 dsp after you have installed VoxWare -3.0 (first time). - -The configuration program asks two DMA channels 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). -The second DMA channel is required for initialization of the microcontroller. -You have to use separate DMA channels. - -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. - -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 wierd. - -Btw, The driver may complain something about "sscapeintr()" after -running ssinit. You should just ignore these messages. - -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) has 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. -It can be used by enabling the stand alone MPU401 support but you have -to initialize it by using the MS-DOS SNDSETUP program. - -There are some other OPTi chips which may be used in soundcards such as -82C930 and MAC32. These chips are not supported by VoxWare yet. Please -contact me if you have a soundcard which uses these chips. - -Some MAD16 based cards may cause feedback, whistle or terrible noise if the -line3 mixer channel is turned too high. - -If you have a MAD16 card which have an OPL4 (FM + Wave table) synthesizer -chip (_not_ an OPL3), you have to apped line containing #define MAD16_OPL4 -to the file linux/dirvers/sound/local.h (after running make config). - -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 -spesific section for instructions about configuring more than one MPU401 cards. - -Logitech Soundman Wave ----------------------- - -Read the above MV Jazz spesific instructions first. - -The Logitech SoundMan Wave (don't confuse 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 MPU401 support if you want to use the OPL4 mode. - -NOTE! Don't answer 'y' when the driver asks about SM Games support - (the next question after the MIDI0001.BIN name). However - aneswering 'y' is not dangerous. - -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 settigs when the machine -is powered on. These cards actually behave just like they have jumpers -for all of the settings. Configure VoxWare for MSS, MPU, SB/SB Pro and OPL3 -supports with these cards. - -The config program asks if you want support for the mixer of -SG NX Pro. Answer 'y' to these questions if you have one of the above 8 or -16 bit Aztech cards. - -There are some new Sound Galaxies in the market. I have no experience with -them so read the card's manual carefully. - - -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 origin of the card. - -Diamond -------- - -The oldest (Sierra Aria based) soundcards made by Diamond are not supported -(they may work if the card is initialized using DOS).

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. - -Others? -------- - -Since there are so many different soundcards, 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 -======================= - -First of all. There is an easy way to make most soundcards to work -with Linux. Just use the DOS based driver to initialize the card -to a _known_ state. Then ctrl-alt-del to Linux. If Linux is configured -to use the sama I/O, IRQ and DMA numbers than DOS, the card could work. - -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 choise. Some cards -don't work in the SB and MSS modes at the same time. - -There are some cards which will be supported by VoxWare sooner or later -(currently at least cards based on the ESS chipset). Such cards are -so common that there is some idea in writing the driver. Check the -VoxWare home page (http://personal.eunet.fi/pp/voxware) for latest -information. - -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 never 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 desicion to not support -obsolete cards. It's possible that someone else makes a separately -distributed driver (diffs) for the card. Version v4.0 will be much more -modular so making separately distributed drivers will be easier with it. -(The bad news is that v4.0 will not be available before late -96). - -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://personal.eunet.fi/pp/voxware). 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. - -Some companies don't give low level technical information about their -products to public or at least their require signing a NDA. - -I have also made decicion to not accept code based on reverse engineering -to VoxWare. 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 withoun any specs will be a pain. The -third reason is that why shoud we help such companies in selling their -products to Linux users when they don't want to sell to Linux users -at all? - -Unfortunately many of the leading soundcard manufacturers are not willing -to co-operate with Linux/Unix community. For example: Creative Technology -doesn't give information about the ASP chip and the Emu synth chip of AWE32 -and SB32. Turtle Beach don't give information about any of their -products. MediaVision requires NDA before they are willing to -give information about the Jazz16 chip (fortunately Logitech gave -the info about SM Wave). - -So at least the above three companies are out until they are willing to -release documentation about their products (the situation is the -same with many DOS based freeware/shareware games and utilities). If -you want to use Linux/Unix with their cards, please don't try to push -me. It's a better idea to contact the manufacturer and explain that -you want to use your card with Linux/Unix. You could also try to sell -your card to somebody else and then buy a card that is supported by VoxWare. - -However it's possible that things change and a driver gets written -for some of the banned cards. Please, don't send me messages asking if -there is any plans to write a driver for the cards mentioned above. I -will put any news to the VoxWare www home page (see below). - -There are some common audio chipsets that are supported yet. For example -the ESS chips and Sierra Aria. It's likely that these architectures -get some support in future but I can't make any promises. Just look -at the home page for latest info. - -Information about unsupported soundcards and chipsets is welcome as well -as free copies of soundcards, SDKs and operating systems. - -If you have any corrections and/or comments, please contact me. - -Hannu Savolainen -hannu@voxware.pp.fi -VoxWare www home page: http://personal.eunet.fi/pp/voxware - diff --git a/sys/i386/isa/sound/Readme.modules b/sys/i386/isa/sound/Readme.modules deleted file mode 100644 index 2dab125..0000000 --- a/sys/i386/isa/sound/Readme.modules +++ /dev/null @@ -1,99 +0,0 @@ -Building a loadable sound driver -================================ - -Loadable module support in version 3.5 of VoxWare is mostly rewritten since -the previous version (3.0.1). This means that some things have changed. - -To compile the sound driver as a loadable module you have to perform -the following steps: - -1) Install modules-1.2.8.tar.gz package (or later if available). -2a) Check that symbol remap_page_range is defined in linux/init/ksyms.c. -Insert a line containing "X(remap_page_range)," if required.

It's no -longer required that the sound driver sources are installed in the -kernel source tree (linux/drivers/sound). When installing a separately -distributed sound driver you may install the sources for example to -/usr/src/sound. -5) Execute make in the sound driver source directory. Enter -configuration parameters as described in Readme.cards. Then just wait until -the driver is compiled OK. -6) Copy sound.o to the directory where insmod expects to find it. -("make install" copies it to /lib/modules/misc). -7) Use command "insmod sound" to load the driver. - -8) The sound driver can be removed using command "rmmod sound". - - -Parameters accepted by the loadable sound driver -================================================ - -Setting DMA buffer size ------------------------ - -The driver allocates a DMA buffer (or two for full duplex devices) -every time the audio device (/dev/dsp or /dev/audio) is opened -and frees it when the device is closed. Size of this buffer is defined -when the driver is configured (the last question). The buffer size -can be redefined when loading the driver if required (note that this is -an optional feature which is not normally required). The buffer size -is redefined by adding dma_pagesize= parameter to the insmod command line. -For example: - - insmod sound dma_buffsize=32768 - -Minimum buffer size is 4096 and the maximum depends on the DMA channe. -For 8 bit channels (0 to 3) the limit is 64k and for 16 bit ones (5 to 7) -it's 128k. Driver selects a suitable buffer size automaticly in case -you try to spesify an invalid size. - -Q: What is the right DMA buffer size? - -A: It depends on the sampling rate, machine speed and the load of the system. -Large buffers are required on slow machines, when recording/playing CD-quality -audio or when there are other processes running on the same system. Also -recording to hard disk is likely to require large buffers. - -Very small buffers are sufficient when you are just playing 8kHz audio files -on an empty P133 system. Using a 128k byffer just wastes 120k (or 250k) -of valuable physical RAM memory. - -The right buffer sice can be easily found by making some experiments -with the dma_buffsize= parameter. I use usually 16k buffers on a DX4/100 system -and 64k on an old 386 system. - -NOTE! DMA buffers are used only by /dev/audio# and /dev/dsp# devices. - Other device files don't use them but there are two exceptions: - GUS driver uses DMA buffers when loading samples to the card. - Ensoniq SoundScape driver uses them when doanloading the microcode - file (sndscape.co[012]) to the card. Using large buffers doesn't - increase performance in these cases. - -Configuring device parameters when loading the driver ------------------------------------------------------ - -The loadable version of the sound driver accepts now the same -sound= parameter that has been available in the LILO command line. -In this way it's possible to change I/O port, IRQ and DMA addresses -and to enable/disable various cards at load time. Normally -the driver uses the configuration parameters entered when compiling -and configuring the driver. -Look at Readme.linux for more info. - -NOTE! This method is not normally required. You should use it only when - you have to use different configuration than normally. The sound= - command line parameter is error phrone and not recommended. - -Debugging and tracing ---------------------- - -Modularized sound driver doesn't display messages during initialization as -the kernel compiled one does.

The /dev/midi## is a raw -tty like interface to MIDI ports. There is a device file for each MIDI -port on your system. They are named (/dev/midi00 to /dev/midiNN). -The second addition is the /dev/music which is higher level interface -than the old /dev/sequencer. It's intended for writing device independent -applications like sequencers. - -/dev/midi## ------------ - -This interface should be usefull for applications like MIDI sysex librarians. -There are (currently) no timing features so making music could be impossible. - -There are as many /dev/midi## devices as there are MIDI ports in the system. -The /dev/midi00 is connected to the first one, /dev/midi01 to the second etc. - -These devices work like tty devices in raw mode. Everything written to them is -sent out to the MIDI port. There is currently an extra delay of at most -1/100th of sec but it will be removed later. - -The reading algorithm is little bit more complicated. There are two different -cases: - -1) There is at least one byte in the input buffer. - -The read returns as many bytes as it can without waiting for more bytes. -For example when a process reads 100 bytes and there are 10 bytes in the -buffer, the read returns just 10 bytes. - -2) The input buffer is empty when the process calls read. - -The read waits for the first byte and then continues as in case 1. By -default it waits infinitely but there is an ioctl for setting a timeout -for this. The ioctl(fd, SNDCTL_MIDI_PRETIME, &time) changes the timeout. -The time is given in 1/10th of seconds (10 means one second). - -Other ioctl calls: - -ioctl(fd, SNDCTL_MIDI_MPUMODE, &mode) is available for full MPU-401 -compatible devices such as MPU-IPC-T, MQ PC Midi Card or MQX-32. -It's not available for the so called MPU UART ports of some soundcards -(PAS16, SB16 etc). By default the MIDI port is in UART mode after open. -If this ioctl is called with mode=1, the interface is put to the intelligent -(coprocessor) mode. NOTE! The MIDI port will be reset when this ioctl is called. -It could have some strange effects if not called immediately after open. This -vall returns EINVAL if the midi port doesn't support the MPU-401 intelligent -mode. - -ioctl(fd, SNDCTL_MIDI_MPUCMD, &cmdstruct) is valid only if the MIDI port -is put to the coprocessor mode using ioctl(SNDCTL_MIDI_MPUMODE). It's used to -send commands to a MPU-401 compatible MIDI cards. Please refer to the -MPU-401 Technical Reference Manual (or Music Quest Technical Reference -Manual) for descriptions of the commands. - -The argument of SNDCTL_MIDI_MPUCOMMAND is of type mpu_command_rec. It -has the following fields: - -typedef struct { - unsigned char cmd; - - char nr_args, nr_returns; - unsigned char data[30]; - } mpu_command_rec; - -where: - cmd Contains the command number. - nr_args Number of arguments of the command. - MUST BE INITIALIZED BEFORE CALL - nr_returns Number of bytes returned by the command. - MUST BE INITIALIZED BEFORE CALL - data Buffer for the command arguments and returned - data. - -Be extremely carefull with the nr_args and nr_returns fields.

The main differences are the following: - -- /dev/sequencer makes the MIDI ports to look like the synth devices. In fact -the result is somewhere between the MIDI specification and the synth devices of -/dev/sequencer. Both kind of devices are accessed using the SEQ_START_NOTE() -like macros. The voice number parameters of the API macros have been redefined -to denote MIDI channels. This means that the driver allocates voices for -the channels automaticly (this is a responsibility/right of an application -with /dev/sequencer). The result is that a SEQ_START_NOTE() macro has -similar effects for a synth channel than on a MIDI port. This kind of -solution provides better device independence than the /dev/sequencer. The -drawback is that the new interface doesn't permit so low level access to the -device as the /dev/sequencer does. An application developer must choose between -these two interfaces. I think the old /dev/sequencer is better for applications -like module players while the new one is better for making generic sequencer -programs. - -- There are no separate MIDI devices with the /dev/sequencer2. The -ioctl(SNDCTL_SEQ_NRMIDIS) returns always zero. Instead the MIDI ports are -shown as synth devices. ioctl(SNDCTL_SEQ_NRSYNTHS) on /dev/sequencer2 will -return sum of internal synthesizers (GUS, OPL3) and MIDI ports in the systems. - -- The new interface is used much like the ordinary /dev/sequencer. The -event format is new so you have to use the API macros defined in the -sys/soundcard.h. The interface is will propably change before the final 3.0 -release but using the API macros should ensure compatibility in source level. -The new event format is not recognized by version 2.X so don't try to -distribute binaries compiled with soundcard.h of v3.X. - -- The basic API useage is similar to the current one. There are some new -macros but the older ones should work as earlier. The most important -incompatibility is that the /dev/sequencer2 driver allocates voices itself. -The other one is that the application must send SEQ_START_TIMER() as its -first event. Otherwise the timer is not started and the application waits -infinitely. - - -There are several new features but I don't document them here. There are -some info in the soundcard.h (near the end). I have also included some -sample code in the directory v30. Full documentation will -appear in the Hacker's Guide later. - -Don't hesitate to contact me in case you have questions or comments. - -Hannu Savolainen -hannu@voxware.pp.fi diff --git a/sys/i386/isa/sound/ad1848.c b/sys/i386/isa/sound/ad1848.c deleted file mode 100644 index 243ed78..0000000 --- a/sys/i386/isa/sound/ad1848.c +++ /dev/null @@ -1,1858 +0,0 @@ -/* - * sound/ad1848.c - * - * Modified by Luigi Rizzo (luigi@iet.unipi.it) - * - * The low level driver for the AD1848/CS4248 codec chip which is used for - * example in the MS Sound System. - * - * The CS4231 which is used in the GUS MAX and some other cards is upwards - * compatible with AD1848 and this driver is able to drive it. - * - * CS4231A and AD1845 are upward compatible with CS4231.
