-Changelog for version 3.5-alpha7
---------------------------------
-
-Since 3.5-alpha6
-- Changed all #ifndef EXCLUDE_xx stuff to #ifdef CONFIG_xx. 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). Note that
-	the base address bust be the base address of the codec chip not the
-	card itself. For the GUS16 these are the same but most MSS compatible
-	cards have the codec located at card_base+4.
-- Some minor changes
-
-Since 2.5 (******* MAJOR REWRITE ***********)
-
-This version is based on v2.3. I have tried to maintain two versions
-together so that this one should have the same features than v2.5.
-Something may still be missing. If you notice such things, please let me
-know.
-
-The Readme.v30 contains more details.
-
-- /dev/midi## devices.
-- /dev/sequencer2
-
-Since 2.5-beta2
-- Some fine tuning to the GUS v3.7 mixer code.
-- Fixed speed limits for the plain SB (1.0 to 2.0).
-
-Since 2.5-beta
-- Fixed OPL-3 detection with SB. Caused problems with PAS16.
-- GUS v3.7 mixer support.
-
-Since 2.4
-- Mixer support for Sound Galaxy NX Pro (define __SGNXPRO__ on your local.h).
-- Fixed truncated sound on /dev/dsp when the device is closed.
-- Linear volume mode for GUS
-- Pitch bends larger than +/- 2 octaves.
-- MIDI recording for SB and SB Pro. (Untested).
-- Some other fixes.
-- SB16 MIDI and DSP drivers only initialized if SB16 actually installed.
-- Implemented better detection for OPL-3. This should be useful if you
-  have an old SB Pro (the non-OPL-3 one) or a SB 2.0 clone which has a OPL-3.
-- SVR4.2 support by Ian Hartas. 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.

-VoxWare v2.90 release notes
---------------------------
-
-
-		This version includes some hidden features which
-		are described in the file experimental.txt
-		Some of these features are not enabled by default. Look at
-		experimental.txt for more info.
-
-		I just decided to release this version with some
-		incompletely implemented features disabled since
-		there are some new features required by a popular 
-		application. In addition there is also support
-		for the GUS MAX and the 16 bit sampling option of GUS.
-
-		The MSS/WSS support works now. At least with SG NX Pro 16.
-
-********* IMPORTANT *****************************************
-Linux 1.0 or later is required to by this driver version.
-
-Don't distribute binaries which use /dev/sequencer and are
-compiled with the soundcard.h of this version. They will
-not work with version 2.x of the driver.
-*************************************************************
-
-
-You will need the snd-util-2.5.tar.gz and snd-data-0.1.tar.Z
-packages to use this driver. They should be in the same
-ftp site or BBS from where you got this driver. For
-example at nic.funet.fi:pub/OS/Linux/*.
-
-If you are looking for the installation instructions, please
-look at linux/Readme.
-
-Compatibility with the earlier versions
----------------------------------------
-
-This version is backward compatible with the version 2.X. All programs
-compiled with sys/soundcard.h of v2.X should work without problems.
-PROGRAMS COMPILED WITH THE sys/soundcard.h OF THIS VERSION WILL NOT
-WORK WITH v2.X DRIVER. BE CAREFUL WHEN DISTRIBUTING BINARIES COMPILED 
-FOR THIS VERSION.

-This sound driver is for FreeBSD 3.0-current .
-
-
-Major enhancement we now support mapping the dma buffer to user
-space for write operations only. This features is useful for 
-games like xquake . So far the mmap features seems to work
-with the GUS PnP Pro and with the SB16. 
-
-For xquake you will need:
-
-1. a few mods to the linux loadable module so just download it and
- replace yours:
-cd /sys/i386/
-tar -xzf linux_ioctl.tar.gz
-cd /usr/src/lkm/linux
-make 
-make install
-modunload -i 0    (if you have the linux up and running)
-linux
-ftp://rah.star-gate.com/linux_ioctl.tar.gz
-
-2. Install the linux lib 2.4 package:
-pkg_add linux_lib-2.4.tgz
-
-ftp://ftp.freebsd.org/pub/FreeBSD/packages-current/emulators/linux_lib-2.4.tgz
-
-If you don't have xquake you can get it from:
-
-3. ftp://ftp.freebsd.org/pub/idgames/idstuff/unsup/intel_linux_quake101.tgz
-
-
-A simple test program mmap_test.c is provided in the sound driver directory.
-So copy it to your home directory or favorite place and compile it.
-cc -o mmap_test mmap_test.c
-
-record a sample session:
-cat /dev/dsp >smpl
-
-now run mmap_test . You will hear a loud pop thats a test program
-then the sample stream will loop .
-
-
-Phew, now back to sound driver land 8)
-
-
-This is a minor sound driver release for  the GUS PnP Pro , GUS MAX,
-AudioTrix Pro , SB16 and SB16 PnP. There is also an experimental
-AWE sub model.
-
-Included Luigi's clean up work . Tnks!
-
-Randall Hopper's SB16 speed setting fix . Tnks!
-
-Fixed signal handling throught out the sound driver. The problem
-first surfaced with the SB16 not generating an interrupt on the
-last dma request and SB afficionados quickly pointed out the 
-bug in the driver. I had to put back the auto dma feature for
-xquake :(
-
-
-NOTE YOU DON'T NEED THE PNP DRIVER FOR THE GUS PNP SINCE THE DRIVER
-HAS BUILTIN PNP SUPPORT FOR THE GUS.
-
-My P133 Bios supports PnP. To first figured out what my SB16 PnP
-was being configured to I booted win95 and checked out what Win95
-ended up with . Alternatively, if you want to you can also down
-load Sujal Patel's PnP driver:
-
- ftp://rah.start-gate.com/pub/FreeBSD-ISA_PnP_June8.tar.gz
-
-follow the instructions on how to configure your PnP soundcard or 
-ISA device.
-Lugi also has  Sujal's PnP driver .

-
-
-cd /sys/i386/conf
-Edit the kernel config file in /sys/i386/conf
-
-IF YOU HAVE A GUS MAX or GUS add the option NOGUSPNP to the config file
-	OPTIONS NOGUSPNP
-  THEN follow the instructions for NONPNP CONFIGURATION
-
-
-PNP CONFIGURATION
-To configure your guspnp PRO if you have a motherboard which supports
-PnP:
-
-	controller snd0
-	device gus0 at isa?
-
-NONPNP CONFIGURATION
-To configure your guspnp PRO if your motherboard does NOT support
-PnP:
-
-device gus0 at isa? port  0x220 irq 11 drq 1 flags 0x3
-
-
-the gus pnp is fully software configurable and the above configuration
-is setup for full duplex audio. The dma channel settings are:
-
-drq 1   	--- DMA channel for playback
-
-flags 0x3	--- DMAN channel for recording
-
-In the event that you have to configure a GUS PnP manually or a GUS MAX:
-
-     Available IRQs for the GUS are:
-     3, 5, 7, 9, 11, 12, 15

-VoxWare v3.5-alpha5 release notes
----------------------------------
-
-IMPORTANT! This version of the driver is compatible only with Linux versions
-	   1.3.33 and later. It may work with earlier ones as a loadable
-	   module but...
-
-	   Also this is an ALPHA test version which has not been tested
-	   with all cards. At least AEDSP16 support will not work. PAS16
-	   and PSS supports have not been tested. /dev/dsp and /dev/audio
- 	   playback with standard GUS sounds scrambled. 16 bit mode of
-	   SB16 doesn't work.
-
-Please read the SOUND-HOWTO (available from sunsite.unc.edu and other Linux ftp 
-sites). It contains much more information than this file.
-
-*****************************************************************
-* NEW! VoxWare home page is http://personal.eunet.fi/pp/voxware *
-* The file Readme.cards contains card specific instructions     *
-* about configuring various cards.				*
-*****************************************************************
-
-There are some programming information (little bit old) in the
-Hacker's Guide 
-(ftp://nic.funet.fi/pub/OS/Linux/ALPHA/sound/snd-sdk-doc-0.1.ps.gz).
-Believe me: The file is really there. The directory is just hidden and
-you have to cd into it before the file is visible. Note: This directory
-was accidently removed some time ago but it's now back.
-
-I have got many patches from various persons during last year. Some of
-them are still on my mailbox and they should be included in versions
-after v3.0 (I will not add aditional features before v3.0 is ready).
-
-   ====================================================
--  THIS VERSION ____REQUIRES____ Linux 1.3.33 OR LATER.
-   ====================================================
-
--  THIS VERSION MAY NOT WORK WITH Linux VERSIONS RELEASED
-   AFTER end of Nov 1995. If this version doesn't compile with
-   your kernel version, please use the sound driver version
-   included in your kernel.
-
-You will need the snd-util-3.0.tar.gz and snd-data-0.1.tar.Z
-packages to use this driver. They should be in the same
-ftp site or BBS from where you got this driver. For
-example at nic.funet.fi:pub/OS/Linux/*.
-
-If you are looking for the installation instructions, please
-look at linux/Readme.
-
-Supported soundcards
---------------------
-
-Gravis Ultrasound (GUS)
-GUS MAX
-GUS with the 16 bit sampling daughtercard
-PAS16
-Windows Sound System compatible soundcards
-ECHO-PSS (cards based on the PSS architecture by Analog Devices.
-	Including Orchid SW32, Cardinal DSP16 among others).
-		(NOTE! WSS mode may not work (DMA channel setup problem)).
-MediaTriX AudioTriX Pro (OPL4 and the optional effect daughtercard
-	require special initialization. There is a program (setfx) in
-	the snd-util-3.0.tar.gz package which does it).
-Ensoniq SoundScape (works but needs some improvements)
-MV Jazz16 based soundcards (ProSonic, 3D etc).
-SoundMan Wave (recording may not work, mixer support is limited)
-Mozart (OAK OTI-601 interface chip) based soundcards.
-MAD16 (an interface chip by OPTi) based soundcards (TB Tropez ???).
-(NOTE! The MAD16 looks similar to the Mozart chip. It could be a good
-idea to configure MAD16 cards as Mozart ones. The MAD16 driver doesn't set
-up MPU401 which the Mozart one does.
-CS4232 based cards such as AcerMagic S23.
-
-
-In addition all Sound Blaster models and clones (up to AWE32) work if
-you want to use them.
-
-The Emu synthesizer chip of AWE32 is not and will not be supported. The same is
-true with the ASP chip also. Creative Technology will not release detailed
-information about them so it's not possible to support them.
-
-If you want to get support for AWE32 or ASP, please contact Creative Labs.
-Ask _politely_ if they are going to support Linux. Maybe they change
-their policy if there is enough demand.
-
-===========================================================================
-If your card is compatible with SB, MPU401 or Windows Sound System, it
-may work with the driver even if it's not listed in the above list. In this
-case it may require initialization using DOS. Just start DOS and cold
-boot to Linux (etc.) by hitting ctrl-alt-del. 
-===========================================================================
-
-Compatibility with the earlier versions
----------------------------------------
-
-There have been some changes in soundcard.h after v2.5 of the driver
-(v2.90 is compatible with this one). Binaries compiled with this version
-of soundcard.h will not work with v2.0 and earlier.
-

-If you have some problems
-=========================
-
-Read the sound HOWTO (sunsite.unc.edu:/pub/Linux/docs/...?).
-Also look at the home page (http://personal.eunet.fi/pp/voxware). It may
-contain info about some recent bug fixes.
-
-It's likely that you have some problems when trying to use the sound driver
-first time. Soundcards don't have standard configuration so there are no
-good default configuration to use. Please try to use same I/O, DMA and IRQ
-values for the soundcard than with DOS.
-
-If you get an error message when trying to use the driver, please look
-at /var/adm/messages for more verbose error message.
-
-
-In general the easiest way to diagnoze problems is to do "cat /dev/sndstat".
-
-If you get an error message, there are some problems with the driver setup:
-
-	- "No such file or directory" tells that the device files for
-	the sound driver are missing. Use the script at the end of
-	linux/drivers/sound/Readme.linux to create them.
-
-	- "No such device" telss that the sound driver is not in the kernel.
-	You have to reconfigure and recompile the kernel to have the sound
-	driver. Compiling the driver doesn't help alone. You have to boot
-	with the newly compiled one before the driver becomes active.
-	The Linux-HOWTO should help in this step.
-
-The following errors are likely with /dev/dsp and /dev/audio.
-
-	- "No such device or address". This error message should not happen
-	with /dev/sndstat but it's possible with the other sound devices.
-	This error indicates that there are no suitable hardware for the
-	device file or the sound driver has been compiled without support for
-	this particular device. For example /dev/audio and /dev/dsp will not
-	work if "digitized voice support" was not enabled during "make config".
-	
-	- "Device or resource busy". Propably the IRQ (or DMA) channel 
-	required by the soundcard is in use by some other device/driver.
-
-	- "I/O error". Almost certainly (99%) it's an IRQ or DMA conflict.
-	Look at the kernel messages in /var/adm/notice for more info.
-
-	- "Invalid argument". The application is calling ioctl()
-	with impossible parameters. Check that the application is
-	for sound driver version 2.X or later.
-
-In general the printout of of /dev/sndstat should tell what is the problem.
-It's possible that there are bugs in the sound driver but 99% of the problems
-reported to me are caused by somehow incorrect setup during "make config".
-
-For owners of TI TM4000M notebooks
-----------------------------------
-
-There appears to be some kind of conflict between the sound support
-(MV Jazz), mouse port and VoxWare. You could try to configure kernel
-with the C&T 82C710 mouse port support disabled.

-Configuring VoxWare 3.0 (for Linux) with some most common soundcards
-====================================================================
-
-NOTE! This document may contain some error. Please inform me
-      if you find any mistakes.
-
-Read this before trying to configure the driver
------------------------------------------------
-
-There are currently many cards that work with VoxWare. Some of the cards
-have native support while the others work since they emulate some other
-cards (usually SB, MSS/WSS and/or MPU401). The following cards have native
-support in VoxWare. 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 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). The recent (LX?)
-models are based on the MAD16 chip which is supported by VoxWare.
-
-Audio Excel DSP16
------------------
-

-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.
-
-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.

-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. The driver will
-not load if this line is missing.
-2b) Recompile kernel with soundcard support disabled.
-3) Boot the new kernel.
-4) cd to the sound driver source directory (this directory). 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. This feature can be turned on by adding
-init_trace=1 to the insmod command line.
-
-For example:
-
-	insmod sound init_trace=1

-VoxWare v3.0
-------------
-
-All features of v2.90-2 should work as earlier. There could be some
-omissions but they are unintentional. I started this version thread
-after v2.3 so all features implemented before it are there.
-
-New features
-============
-
-There are now two new device interfaces. 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. They
-must match the command. An incorrect value will put the card and
-the driver out of sync. Refer to the MPU-401/MQX-32M documentation for further
-datails.
-
-
-
-/dev/music (/dev/sequencer2)
-----------------------------
-
-This device file works much like the /dev/sequencer which has been present
-since the beginning. 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.

- * 
- * The CS4231 which is used in the GUS MAX and some other cards is upwards

- * CS4232 is a PnP audio chip which contains a CS4231A (and SB, MPU). CS4232A is
- * an improved version of CS4232.
- * 
- * CS4236 is also a PnP audio chip similar to the 4232
- *
- * OPTi931 is another high-end 1848-type chip. It differs in the use

- * OPTi 82C929     MAD16 Pro
- * 
- * These audio interface chips don't prduce sound themselves. They just connect
- * some other components (OPL-[234] and a WSS compatible codec) to the PC bus
- * and perform I/O, DMA and IRQ address decoding. There is also a UART for
- * the MPU-401 mode (not 82C928/Mozart). The Mozart chip appears to be
- * compatible with the 82C928 (can anybody confirm this?).
- * 
- * NOTE! If you want to set CD-ROM address and/or joystick enable, define
- * MAD16_CONF in local.h as combination of the following bits:
- * 
- * 0x01    - joystick disabled
- * 
- * CD-ROM type selection (select just one): 0x00    - none 0x02    - Sony 31A
- * 0x04    - Mitsumi 0x06    - Panasonic (type "LaserMate", not
- * "SoundBlaster") 0x08    - Secondary IDE (address 0x170) 0x0a    - Primary
- * IDE (address 0x1F0)
- * 
- * For example Mitsumi with joystick disabled = 0x04|0x01 = 0x05 For example
- * LaserMate (for use with sbpcd) plus joystick = 0x06
- * 
- * MAD16_CDSEL: This defaults to CD I/O 0x340, no IRQ and DMA3 (DMA5 with
- * Mitsumi or IDE). If you like to change these, define MAD16_CDSEL with the
- * following bits:
- * 
- * CD-ROM port: 0x00=340, 0x40=330, 0x80=360 or 0xc0=320 OPL4 select: 0x20=OPL4,
- * 0x00=OPL3 CD-ROM irq: 0x00=disabled, 0x04=IRQ5, 0x08=IRQ7, 0x0a=IRQ3,
- * 0x10=IRQ9, 0x14=IRQ10 and 0x18=IRQ11.
- * 
- * CD-ROM DMA (Sony or Panasonic): 0x00=DMA3, 0x01=DMA2, 0x02=DMA1 or
- * 0x03=disabled or CD-ROM DMA (Mitsumi or IDE):    0x00=DMA5, 0x01=DMA6,
- * 0x02=DMA7 or 0x03=disabled
- * 
- * For use with sbpcd, address 0x340, set MAD16_CDSEL to 0x03 or 0x23.

- *	The OPL-3 mode is switched on by writing 0x01, to the offset 5
- *	of the right side.
- *
- *	Another special register at the right side is at offset 4. It contains
- *	a bit mask defining which voices are used as 4 OP voices.
- *
- *	The percussive mode is implemented in the left side only.
- *
- *	With the above exeptions the both sides can be operated independently.
- *	
- *	A 4 OP voice can be created by setting the corresponding
- *	bit at offset 4 of the right side.
- *
- *	For example setting the rightmost bit (0x01) changes the
- *	first voice on the right side to the 4 OP mode. The fourth
- *	voice is made inaccessible.
- *
- *	If a voice is set to the 2 OP mode, it works like 2 OP modes
- *	of the original YM3812 (AdLib). In addition the voice can 
- *	be connected the left, right or both stereo channels. It can
- *	even be left unconnected. This works with 4 OP voices also.
- *
- *	The stereo connection bits are located in the FEEDBACK_CONNECTION
- *	register of the voice (0xC0-0xC8). In 4 OP voices these bits are
- *	in the second half of the voice.

-
-Instructions on using audio on a FreeBSD 2.1 (or 2.0-current) system.
-See also /sys/i386/conf/LINT.
-
-To enable sound driver support, the controller sound code must be included
-in your config file:
-
-# SB = SoundBlaster;  PAS = ProAudioSpectrum;  GUS = Gravis UltraSound
-# Controls all sound devices
-controller	snd0
-
-Uncomment one or more of these device entries, depending on what type of
-sound card you have:
-
-# ProAudioSpectrum PCM and Midi - for PAS
-#device pas0     at isa? port 0x388 irq 10 drq 6
-
-# SoundBlaster DSP driver - for SB, SB Pro, SB16, PAS(emulating SB)
-#device sb0      at isa? port 0x220 irq 7 drq 1
-
-# SoundBlaster 16 DSP driver - for SB16 - requires sb0 device
-#device sbxvi0   at isa? drq 5
-
-# SoundBlaster 16 MIDI - for SB16 - requires sb0 device
-#device sbmidi0  at isa? port 0x300
-
-# Gravis UltraSound - for GUS, GUS16, GUSMAX
-# For cards that use 2 DMA Channels:
-#     drq = Write DMA Channel, flags = Read DMA Channel
-#device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3
-
-# Gravis UltraSound 16 bit option - for GUS16 - requires gus0
-#device gusxvi0 at isa? port 0x530 irq 7 drq 3
-
-# MS Sound System (AD1848 Based Boards)
-#device mss0 at isa? port 0x530 irq 10 drq 1
-
-# Yamaha OPL-2/OPL-3 FM - for SB, SB Pro, SB16, PAS
-#device opl0     at isa? port 0x388
-
-# MPU-401 - for MPU-401 standalone card
-#device mpu0     at isa? port 0x330 irq 6 drq 0
-
-# 6850 UART Midi
-#device uart0 at isa? port 0x330 irq 5
-
-You may add one or more of the following depending on what you do and don't
-want compiled into your kernel.  Note:  Excluding things with EXCLUDE_... 
-is NOT recommended unless you really know what you're doing.
-
-#options 	EXCLUDE_AUDIO			# NO digital audio support
-#options 	EXCLUDE_SEQUENCER		# NO sequencer support
-#options	EXCLUDE_MIDI			# NO MIDI support whatsoever
-#options 	EXCLUDE_SBPRO			# EXCLUDE SB Pro support
-#options 	EXCLUDE_SB_EMULATION		# NO PAS SB emulation support
-#options 	EXCLUDE_GUS_IODETECT		# NO GUS io detection
-#options 	EXCLUDE_PRO_MIDI		# NO PAS MIDI support
-
-Other Options:
-
-#options	SYMPHONY_PAS
-	Adds some code to make pas work with Symphony chipsets.  Only use
-	this if your pas doesn't work and you have a Symphony chipset.
-
-#options	BROKEN_BUS_CLOCK
-	Some systems with the OPTI chipset and a PAS will require you to
-	use this option.  Symptoms are that you will hear a lot of clicking and
-	popping sounds, like a geiger counter, coming out of the PAS even when
-	it is not playing anything.
-
-#options	MOZART_PORT
-	Adds support for Mozart (OAK OTI-601). (Part of the MSS driver)
-
-#options	OPTI_MAD16_PORT
-	Adds support for the OPTI MAD16 Chip. (Part of the MSS driver)
-	If your soundcard has a chip labeled "OPTi 82C929" then try this.
-
-#options	__SGNXPRO__
-	Adds support for the SG NX Pro mixer. (Part of the SB driver)
-
-#options	JAZZ16
-	Adds support for the MV Jazz16 (ProSonic etc). (Part of the SB Driver)
-
-#options	SM_WAVE
-	Adds support for the SoundMan Wave (Part of the SB Driver)
-	Note:  You will need to do some work to get this to work.
-	       See i386/isa/sound/configure.c
-
-#options	SM_GAMES
-	Adds support for the Logitech SoundMan Games (Part of the SB Driver)
-
-#options	PAS_JOYSTICK_ENABLE
-	Enables the gameport on the ProAudio Spectrum
-
-NOTE:  The MPU-401 driver may or may not work, and is unfortunately
-unverifiable since no one I know has one.  If you can test this,
-please let me know!  Also note that you will have to change these
-settings if your soundcard is set for a non-standard address or IRQ.
-Please check your documentation (or verify with any provided DOS utilities
-that may have come with your card) and set the IRQ or address fields
-accordingly.
-
-
-Also:  You can configure more then one card on a single DMA using 
-the conflicts keyword in your configuration file.  This is useful for boards
-with more then one type of emulation.
-
-
-Probing problems:  Since the SB16 uses the same IRQ and addresses for
-the different drivers, some of the snd drivers will not be probed because
-the kernel thinks there is a conflict.  This can be worked-around by
-using the "conflicts" keyword on the sb16's device line.

-/*
- *	Private events for Gravis Ultrasound (GUS)
- *
- *	Format:
- *		byte 0 		- SEQ_PRIVATE (0xfe)
- *		byte 1 		- Synthesizer device number (0-N)
- *		byte 2 		- Command (see below)
- *		byte 3 		- Voice number (0-31)
- *		bytes 4 and 5	- parameter P1 (u_short)
- *		bytes 6 and 7	- parameter P2 (u_short)
- *
- *	Commands:
- *		Each command affects one voice defined in byte 3.
- *		Unused parameters (P1 and/or P2 *MUST* be initialized to zero).
- *		_GUS_NUMVOICES	- Sets max. number of concurrent voices (P1=14-31, default 16)
- *		_GUS_VOICESAMPLE- ************ OBSOLETE *************
- *		_GUS_VOICEON	- Starts voice (P1=voice mode)
- *		_GUS_VOICEOFF	- Stops voice (no parameters)
- *		_GUS_VOICEFADE	- Stops the voice smoothly.
- *		_GUS_VOICEMODE	- Alters the voice mode, don't start or stop voice (P1=voice mode)
- *		_GUS_VOICEBALA	- Sets voice balence (P1, 0=left, 7=middle and 15=right, default 7)
- *		_GUS_VOICEFREQ	- Sets voice (sample) playback frequency (P1=Hz)
- *		_GUS_VOICEVOL	- Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
- *		_GUS_VOICEVOL2	- Sets voice volume (P1=volume, 0xfff=max, 0xeff=half, 0x000=off)
- *				  (Like GUS_VOICEVOL but doesn't change the hw
- *				  volume. It just updates volume in the voice table).
- *
- *		_GUS_RAMPRANGE	- Sets limits for volume ramping (P1=low volume, P2=high volume)
- *		_GUS_RAMPRATE	- Sets the speed for volume ramping (P1=scale, P2=rate)
- *		_GUS_RAMPMODE	- Sets the volume ramping mode (P1=ramping mode)
- *		_GUS_RAMPON	- Starts volume ramping (no parameters)
- *		_GUS_RAMPOFF	- Stops volume ramping (no parameters)
- *		_GUS_VOLUME_SCALE - Changes the volume calculation constants
- *				  for all voices.
