|  |  | 
|  | 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 from Documentation/Configure.help | 
|  | 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.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.conf for pas2, sb and opl3 | 
|  | respectively. |
