-and others whose names I could not find.
-
-This documentation is relevant for the PAS16 driver (pas2_card.c and
-friends) under kernel version 2.3.99 and later. If you are
-unfamiliar with configuring sound under Linux, please read the
-Sound-HOWTO, Documentation/sound/oss/Introduction and other
-relevant docs first.
-
-The following information is relevant information from README.OSS
-and legacy docs for the Pro Audio Spectrum 16 (PAS16):
-==================================================================
-
-The pas2_card.c driver supports the following cards --
-Pro Audio Spectrum 16 (PAS16) and compatibles:
- Pro Audio Spectrum 16
- Pro Audio Studio 16
- Logitech Sound Man 16
- NOTE! The original Pro Audio Spectrum as well as the PAS+ are not
- and will not be supported by the driver.
-
-The sound driver configuration dialog
--------------------------------------
-
-Sound configuration starts by making some yes/no questions. Be careful
-when answering to these questions since answering y to a question may
-prevent some later ones from being asked. For example don't answer y to
-the question about (PAS16) if you don't really have a PAS16. Sound
-configuration may also be made modular by answering m to configuration
-options presented.
-
-Note also that all questions may not be asked. The configuration program
-may disable some questions depending on the earlier choices. It may also
-select some options automatically as well.
-
- "ProAudioSpectrum 16 support",
- - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_,
- Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that
- you read the above list correctly). Don't answer 'y' if you
- have some other card made by Media Vision or Logitech since they
- are not PAS16 compatible.
- NOTE! Since 3.5-beta10 you need to enable SB support (next question)
- if you want to use the SB emulation of PAS16. It's also possible to
- the emulation if you want to use a true SB card together with PAS16
- (there is another question about this that is asked later).
-
- "Generic OPL2/OPL3 FM synthesizer support",
- - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
- The PAS16 has an OPL3-compatible FM chip.
-
-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).
-
-
-The new stuff for 2.3.99 and later
-============================================================================
-The following configuration options are relevant to configuring the PAS16:
-
-Sound card support
-CONFIG_SOUND
- If you have a sound card in your computer, i.e. if it can say more
- than an occasional beep, say Y. Be sure to have all the information
- about your sound card and its configuration down (I/O port,
- interrupt and DMA channel), because you will be asked for it.
-
- You want to read the Sound-HOWTO, available from
- http://www.tldp.org/docs.html#howto . General information
- about the modular sound system is contained in the files
- Documentation/sound/oss/Introduction. The file
- Documentation/sound/oss/README.OSS contains some slightly outdated but
- still useful information as well.
-
-OSS sound modules
-CONFIG_SOUND_OSS
- OSS is the Open Sound System suite of sound card drivers. They make
- sound programming easier since they provide a common API. Say Y or M
- here (the module will be called sound.o) if you haven't found a
- driver for your sound card above, then pick your driver from the
- list below.
-
-Persistent DMA buffers
-CONFIG_SOUND_DMAP
- Linux can often have problems allocating DMA buffers for ISA sound
- cards on machines with more than 16MB of RAM. This is because ISA
- DMA buffers must exist below the 16MB boundary and it is quite
- possible that a large enough free block in this region cannot be
- found after the machine has been running for a while. If you say Y
- here the DMA buffers (64Kb) will be allocated at boot time and kept
- until the shutdown. This option is only useful if you said Y to
- "OSS sound modules", above. If you said M to "OSS sound modules"
- then you can get the persistent DMA buffer functionality by passing
- the command-line argument "dmabuf=1" to the sound.o module.
-
- Say y here for PAS16.
-
-ProAudioSpectrum 16 support
-CONFIG_SOUND_PAS
- Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio
- 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have
- some other card made by Media Vision or Logitech since they are not
- PAS16 compatible. It is not necessary to enable the separate
- Sound Blaster support; it is included in the PAS driver.
-
- If you compile the driver into the kernel, you have to add
- "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2>
- to the kernel command line.
-
-FM Synthesizer (YM3812/OPL-3) support
-CONFIG_SOUND_YM3812
- 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 (I don't currently know of any such
- cards, however).
- Please read the file Documentation/sound/oss/OPL3 if your card has an
- OPL3 chip.
- If you compile the driver into the kernel, you have to add
- "opl3=<io>" to the kernel command line.
-
- If you compile your drivers into the kernel, you MUST configure
- OPL3 support as a module for PAS16 support to work properly.
- You can then get OPL3 functionality by issuing the command:
- insmod opl3
- In addition, you must either add the following line to
- /etc/modprobe.d/*.conf:
- options opl3 io=0x388
- or else add the following line to /etc/lilo.conf:
- opl3=0x388
-
-
-EXAMPLES
-===================================================================
-To use the PAS16 in my computer I have enabled the following sound
-configuration options:
-
-CONFIG_SOUND=y
-CONFIG_SOUND_OSS=y
-CONFIG_SOUND_TRACEINIT=y
-CONFIG_SOUND_DMAP=y
-CONFIG_SOUND_PAS=y
-CONFIG_SOUND_SB=n
-CONFIG_SOUND_YM3812=m
-
-I have also included the following append line in /etc/lilo.conf:
-append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388"
-
-The io address of 0x388 is default configuration on the PAS16. The
-irq of 10 and dma of 3 may not match your installation. The above
-configuration enables PAS16, 8-bit Soundblaster and OPL3
-functionality. If Soundblaster functionality is not desired, the
-following line would be appropriate:
-append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388"
-
-If sound is built totally modular, the above options may be
-specified in /etc/modprobe.d/*.conf for pas2, sb and opl3
-respectively.
