| 9 | This documentation is relevant for the PAS16 driver (pas2_card.c and |
| 10 | friends) under kernel version 2.3.99 and later. If you are |
| 11 | unfamiliar with configuring sound under Linux, please read the |
| 12 | Sound-HOWTO, Documentation/sound/oss/Introduction and other |
| 13 | relevant docs first. |
| 14 | |
| 15 | The following information is relevant information from README.OSS |
| 16 | and legacy docs for the Pro Audio Spectrum 16 (PAS16): |
| 17 | ================================================================== |
| 18 | |
| 19 | The pas2_card.c driver supports the following cards -- |
| 20 | Pro Audio Spectrum 16 (PAS16) and compatibles: |
| 21 | Pro Audio Spectrum 16 |
| 22 | Pro Audio Studio 16 |
| 23 | Logitech Sound Man 16 |
| 24 | NOTE! The original Pro Audio Spectrum as well as the PAS+ are not |
| 25 | and will not be supported by the driver. |
| 26 | |
| 27 | The sound driver configuration dialog |
| 28 | ------------------------------------- |
| 29 | |
| 30 | Sound configuration starts by making some yes/no questions. Be careful |
| 31 | when answering to these questions since answering y to a question may |
| 32 | prevent some later ones from being asked. For example don't answer y to |
| 33 | the question about (PAS16) if you don't really have a PAS16. Sound |
| 34 | configuration may also be made modular by answering m to configuration |
| 35 | options presented. |
| 36 | |
| 37 | Note also that all questions may not be asked. The configuration program |
| 38 | may disable some questions depending on the earlier choices. It may also |
| 39 | select some options automatically as well. |
| 40 | |
| 41 | "ProAudioSpectrum 16 support", |
| 42 | - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_, |
| 43 | Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that |
| 44 | you read the above list correctly). Don't answer 'y' if you |
| 45 | have some other card made by Media Vision or Logitech since they |
| 46 | are not PAS16 compatible. |
| 47 | NOTE! Since 3.5-beta10 you need to enable SB support (next question) |
| 48 | if you want to use the SB emulation of PAS16. It's also possible to |
| 49 | the emulation if you want to use a true SB card together with PAS16 |
| 50 | (there is another question about this that is asked later). |
| 51 | |
| 52 | "Generic OPL2/OPL3 FM synthesizer support", |
| 53 | - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4). |
| 54 | The PAS16 has an OPL3-compatible FM chip. |
| 55 | |
| 56 | With PAS16 you can use two audio device files at the same time. /dev/dsp (and |
| 57 | /dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and |
| 58 | /dev/audio1) is connected to the SB emulation (8 bit mono only). |
| 59 | |
| 60 | |
| 61 | The new stuff for 2.3.99 and later |
| 62 | ============================================================================ |
| 63 | The following configuration options from Documentation/Configure.help |
| 64 | are relevant to configuring the PAS16: |
| 65 | |
| 66 | Sound card support |
| 67 | CONFIG_SOUND |
| 68 | If you have a sound card in your computer, i.e. if it can say more |
| 69 | than an occasional beep, say Y. Be sure to have all the information |
| 70 | about your sound card and its configuration down (I/O port, |
| 71 | interrupt and DMA channel), because you will be asked for it. |
| 72 | |
| 73 | You want to read the Sound-HOWTO, available from |
| 74 | http://www.tldp.org/docs.html#howto . General information |
| 75 | about the modular sound system is contained in the files |
| 76 | Documentation/sound/oss/Introduction. The file |
| 77 | Documentation/sound/oss/README.OSS contains some slightly outdated but |
| 78 | still useful information as well. |
| 79 | |
| 80 | OSS sound modules |
| 81 | CONFIG_SOUND_OSS |
| 82 | OSS is the Open Sound System suite of sound card drivers. They make |
| 83 | sound programming easier since they provide a common API. Say Y or M |
| 84 | here (the module will be called sound.o) if you haven't found a |
| 85 | driver for your sound card above, then pick your driver from the |
| 86 | list below. |
| 87 | |
| 88 | Persistent DMA buffers |
| 89 | CONFIG_SOUND_DMAP |
| 90 | Linux can often have problems allocating DMA buffers for ISA sound |
| 91 | cards on machines with more than 16MB of RAM. This is because ISA |
| 92 | DMA buffers must exist below the 16MB boundary and it is quite |
| 93 | possible that a large enough free block in this region cannot be |
| 94 | found after the machine has been running for a while. If you say Y |
| 95 | here the DMA buffers (64Kb) will be allocated at boot time and kept |
| 96 | until the shutdown. This option is only useful if you said Y to |
| 97 | "OSS sound modules", above. If you said M to "OSS sound modules" |
| 98 | then you can get the persistent DMA buffer functionality by passing |
| 99 | the command-line argument "dmabuf=1" to the sound.o module. |
| 100 | |
| 101 | Say y here for PAS16. |
| 102 | |
| 103 | ProAudioSpectrum 16 support |
| 104 | CONFIG_SOUND_PAS |
| 105 | Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio |
| 106 | 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have |
| 107 | some other card made by Media Vision or Logitech since they are not |
| 108 | PAS16 compatible. It is not necessary to enable the separate |
| 109 | Sound Blaster support; it is included in the PAS driver. |
| 110 | |
| 111 | If you compile the driver into the kernel, you have to add |
| 112 | "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2> |
| 113 | to the kernel command line. |
| 114 | |
| 115 | FM Synthesizer (YM3812/OPL-3) support |
| 116 | CONFIG_SOUND_YM3812 |
| 117 | Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4). |
| 118 | Answering Y is usually a safe and recommended choice, however some |
| 119 | cards may have software (TSR) FM emulation. Enabling FM support with |
| 120 | these cards may cause trouble (I don't currently know of any such |
| 121 | cards, however). |
| 122 | Please read the file Documentation/sound/oss/OPL3 if your card has an |
| 123 | OPL3 chip. |
| 124 | If you compile the driver into the kernel, you have to add |
| 125 | "opl3=<io>" to the kernel command line. |
| 126 | |
| 127 | If you compile your drivers into the kernel, you MUST configure |
| 128 | OPL3 support as a module for PAS16 support to work properly. |
| 129 | You can then get OPL3 functionality by issuing the command: |
| 130 | insmod opl3 |
| 131 | In addition, you must either add the following line to |
| 132 | /etc/modprobe.conf: |
| 133 | options opl3 io=0x388 |
| 134 | or else add the following line to /etc/lilo.conf: |
| 135 | opl3=0x388 |
| 136 | |
| 137 | |
| 138 | EXAMPLES |
| 139 | =================================================================== |
| 140 | To use the PAS16 in my computer I have enabled the following sound |
| 141 | configuration options: |
| 142 | |
| 143 | CONFIG_SOUND=y |
| 144 | CONFIG_SOUND_OSS=y |
| 145 | CONFIG_SOUND_TRACEINIT=y |
| 146 | CONFIG_SOUND_DMAP=y |
| 147 | CONFIG_SOUND_PAS=y |
| 148 | CONFIG_SOUND_SB=n |
| 149 | CONFIG_SOUND_YM3812=m |
| 150 | |
| 151 | I have also included the following append line in /etc/lilo.conf: |
| 152 | append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388" |
| 153 | |
| 154 | The io address of 0x388 is default configuration on the PAS16. The |
| 155 | irq of 10 and dma of 3 may not match your installation. The above |
| 156 | configuration enables PAS16, 8-bit Soundblaster and OPL3 |
| 157 | functionality. If Soundblaster functionality is not desired, the |
| 158 | following line would be appropriate: |
| 159 | append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388" |
| 160 | |
| 161 | If sound is built totally modular, the above options may be |
| 162 | specified in /etc/modprobe.conf for pas2, sb and opl3 |
| 163 | respectively. |
