1 Pro Audio Spectrum 16 for 2.3.99 and later 2 ========================================= 3 by Thomas Molina (firstname.lastname@example.org) 4 last modified 3 Mar 2001 5 Acknowledgement to Axel Boldt (email@example.com) for stuff taken 6 from Configure.help, Riccardo Facchetti for stuff from README.OSS, 7 and others whose names I could not find. 8 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 are relevant to configuring the PAS16: 64 65 Sound card support 66 CONFIG_SOUND 67 If you have a sound card in your computer, i.e. if it can say more 68 than an occasional beep, say Y. Be sure to have all the information 69 about your sound card and its configuration down (I/O port, 70 interrupt and DMA channel), because you will be asked for it. 71 72 You want to read the Sound-HOWTO, available from 73 http://www.tldp.org/docs.html#howto . General information 74 about the modular sound system is contained in the files 75 Documentation/sound/oss/Introduction. The file 76 Documentation/sound/oss/README.OSS contains some slightly outdated but 77 still useful information as well. 78 79 OSS sound modules 80 CONFIG_SOUND_OSS 81 OSS is the Open Sound System suite of sound card drivers. They make 82 sound programming easier since they provide a common API. Say Y or M 83 here (the module will be called sound.o) if you haven't found a 84 driver for your sound card above, then pick your driver from the 85 list below. 86 87 Persistent DMA buffers 88 CONFIG_SOUND_DMAP 89 Linux can often have problems allocating DMA buffers for ISA sound 90 cards on machines with more than 16MB of RAM. This is because ISA 91 DMA buffers must exist below the 16MB boundary and it is quite 92 possible that a large enough free block in this region cannot be 93 found after the machine has been running for a while. If you say Y 94 here the DMA buffers (64Kb) will be allocated at boot time and kept 95 until the shutdown. This option is only useful if you said Y to 96 "OSS sound modules", above. If you said M to "OSS sound modules" 97 then you can get the persistent DMA buffer functionality by passing 98 the command-line argument "dmabuf=1" to the sound.o module. 99 100 Say y here for PAS16. 101 102 ProAudioSpectrum 16 support 103 CONFIG_SOUND_PAS 104 Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio 105 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have 106 some other card made by Media Vision or Logitech since they are not 107 PAS16 compatible. It is not necessary to enable the separate 108 Sound Blaster support; it is included in the PAS driver. 109 110 If you compile the driver into the kernel, you have to add 111 "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2> 112 to the kernel command line. 113 114 FM Synthesizer (YM3812/OPL-3) support 115 CONFIG_SOUND_YM3812 116 Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4). 117 Answering Y is usually a safe and recommended choice, however some 118 cards may have software (TSR) FM emulation. Enabling FM support with 119 these cards may cause trouble (I don't currently know of any such 120 cards, however). 121 Please read the file Documentation/sound/oss/OPL3 if your card has an 122 OPL3 chip. 123 If you compile the driver into the kernel, you have to add 124 "opl3=<io>" to the kernel command line. 125 126 If you compile your drivers into the kernel, you MUST configure 127 OPL3 support as a module for PAS16 support to work properly. 128 You can then get OPL3 functionality by issuing the command: 129 insmod opl3 130 In addition, you must either add the following line to 131 /etc/modprobe.d/*.conf: 132 options opl3 io=0x388 133 or else add the following line to /etc/lilo.conf: 134 opl3=0x388 135 136 137 EXAMPLES 138 =================================================================== 139 To use the PAS16 in my computer I have enabled the following sound 140 configuration options: 141 142 CONFIG_SOUND=y 143 CONFIG_SOUND_OSS=y 144 CONFIG_SOUND_TRACEINIT=y 145 CONFIG_SOUND_DMAP=y 146 CONFIG_SOUND_PAS=y 147 CONFIG_SOUND_SB=n 148 CONFIG_SOUND_YM3812=m 149 150 I have also included the following append line in /etc/lilo.conf: 151 append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388" 152 153 The io address of 0x388 is default configuration on the PAS16. The 154 irq of 10 and dma of 3 may not match your installation. The above 155 configuration enables PAS16, 8-bit Soundblaster and OPL3 156 functionality. If Soundblaster functionality is not desired, the 157 following line would be appropriate: 158 append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388" 159 160 If sound is built totally modular, the above options may be 161 specified in /etc/modprobe.d/*.conf for pas2, sb and opl3 162 respectively.
