            Acknowledgement to Axel Boldt (boldt@math.ucsb.edu) for stuff taken

            
            from Configure.help, Riccardo Facchetti for stuff from README.OSS,

            
            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.

	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

	"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.
