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 from Documentation/Configure.help
64 are relevant to configuring the PAS16:
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.
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.
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
88 Persistent DMA buffers
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.
101 Say y here for PAS16.
103 ProAudioSpectrum 16 support
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.
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.
115 FM Synthesizer (YM3812/OPL-3) support
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
122 Please read the file Documentation/sound/oss/OPL3 if your card has an
124 If you compile the driver into the kernel, you have to add
125 "opl3=<io>" to the kernel command line.
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:
131 In addition, you must either add the following line to
133 options opl3 io=0x388
134 or else add the following line to /etc/lilo.conf:
139 ===================================================================
140 To use the PAS16 in my computer I have enabled the following sound
141 configuration options:
145 CONFIG_SOUND_TRACEINIT=y
149 CONFIG_SOUND_YM3812=m
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"
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"
161 If sound is built totally modular, the above options may be
162 specified in /etc/modprobe.conf for pas2, sb and opl3
