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.
