1Pro Audio Spectrum 16 for 2.3.99 and later 2========================================= 3by Thomas Molina (tmolina@home.com) 4last modified 3 Mar 2001 5Acknowledgement to Axel Boldt (boldt@math.ucsb.edu) for stuff taken 6from Configure.help, Riccardo Facchetti for stuff from README.OSS, 7and others whose names I could not find. 8 9This documentation is relevant for the PAS16 driver (pas2_card.c and 10friends) under kernel version 2.3.99 and later. If you are 11unfamiliar with configuring sound under Linux, please read the 12Sound-HOWTO, Documentation/sound/oss/Introduction and other 13relevant docs first. 14 15The following information is relevant information from README.OSS 16and legacy docs for the Pro Audio Spectrum 16 (PAS16): 17================================================================== 18 19The pas2_card.c driver supports the following cards -- 20Pro 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 27The sound driver configuration dialog 28------------------------------------- 29 30Sound configuration starts by making some yes/no questions. Be careful 31when answering to these questions since answering y to a question may 32prevent some later ones from being asked. For example don't answer y to 33the question about (PAS16) if you don't really have a PAS16. Sound 34configuration may also be made modular by answering m to configuration 35options presented. 36 37Note also that all questions may not be asked. The configuration program 38may disable some questions depending on the earlier choices. It may also 39select 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 56With 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 61The new stuff for 2.3.99 and later 62============================================================================ 63The following configuration options from Documentation/Configure.help 64are relevant to configuring the PAS16: 65 66Sound card support 67CONFIG_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 80OSS sound modules 81CONFIG_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 88Persistent DMA buffers 89CONFIG_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 103ProAudioSpectrum 16 support 104CONFIG_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 115FM Synthesizer (YM3812/OPL-3) support 116CONFIG_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 138EXAMPLES 139=================================================================== 140To use the PAS16 in my computer I have enabled the following sound 141configuration options: 142 143CONFIG_SOUND=y 144CONFIG_SOUND_OSS=y 145CONFIG_SOUND_TRACEINIT=y 146CONFIG_SOUND_DMAP=y 147CONFIG_SOUND_PAS=y 148CONFIG_SOUND_SB=n 149CONFIG_SOUND_YM3812=m 150 151I have also included the following append line in /etc/lilo.conf: 152append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388" 153 154The io address of 0x388 is default configuration on the PAS16. The 155irq of 10 and dma of 3 may not match your installation. The above 156configuration enables PAS16, 8-bit Soundblaster and OPL3 157functionality. If Soundblaster functionality is not desired, the 158following line would be appropriate: 159append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388" 160 161If sound is built totally modular, the above options may be 162specified in /etc/modprobe.conf for pas2, sb and opl3 163respectively. 164
