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
15 The following information is relevant information from README.OSS
16 and legacy docs for the Pro Audio Spectrum 16 (PAS16):
17 ==================================================================
19 The pas2_card.c driver supports the following cards --
20 Pro Audio Spectrum 16 (PAS16) and compatibles:
24 NOTE! The original Pro Audio Spectrum as well as the PAS+ are not
25 and will not be supported by the driver.
27 The sound driver configuration dialog
28 -------------------------------------
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
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.
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).
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.
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).
61 The new stuff for 2.3.99 and later
62 ============================================================================
63 The following configuration options are relevant to configuring the PAS16:
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.
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.
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
87 Persistent DMA buffers
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.
100 Say y here for PAS16.
102 ProAudioSpectrum 16 support
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.
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.
114 FM Synthesizer (YM3812/OPL-3) support
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
121 Please read the file Documentation/sound/oss/OPL3 if your card has an
123 If you compile the driver into the kernel, you have to add
124 "opl3=<io>" to the kernel command line.
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:
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:
138 ===================================================================
139 To use the PAS16 in my computer I have enabled the following sound
140 configuration options:
144 CONFIG_SOUND_TRACEINIT=y
148 CONFIG_SOUND_YM3812=m
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"
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"
160 If sound is built totally modular, the above options may be
161 specified in /etc/modprobe.d/*.conf for pas2, sb and opl3
