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, linux/Documentation/sound/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 "Sound Blaster support",
52 - Answer 'y' if you have an original SB card made by Creative Labs
53 or a full 100% hardware compatible clone (like Thunderboard or
54 SM Games). If your card was in the list of supported cards (above),
55 please look at the card specific instructions later in this file
56 before answering this question. For an unknown card you may answer
57 'y' if the card claims to be SB compatible.
58 Enable this option also with PAS16.
59
60 "Generic OPL2/OPL3 FM synthesizer support",
61 - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
62 The PAS16 has an OPL3-compatible FM chip.
63
64 With PAS16 you can use two audio device files at the same time. /dev/dsp (and
65 /dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and
66 /dev/audio1) is connected to the SB emulation (8 bit mono only).
67
68
69 The new stuff for 2.3.99 and later
70 ============================================================================
71 The following configuration options from linux/Documentation/Configure.help
72 are relevant to configuring the PAS16:
73
74 Sound card support
75 CONFIG_SOUND
76 If you have a sound card in your computer, i.e. if it can say more
77 than an occasional beep, say Y. Be sure to have all the information
78 about your sound card and its configuration down (I/O port,
79 interrupt and DMA channel), because you will be asked for it.
80
81 You want to read the Sound-HOWTO, available from
82 http://www.linuxdoc.org/docs.html#howto . General information
83 about the modular sound system is contained in the files
84 Documentation/sound/Introduction. The file
85 Documentation/sound/README.OSS contains some slightly outdated but
86 still useful information as well.
87
88 OSS sound modules
89 CONFIG_SOUND_OSS
90 OSS is the Open Sound System suite of sound card drivers. They make
91 sound programming easier since they provide a common API. Say Y or M
92 here (the module will be called sound.o) if you haven't found a
93 driver for your sound card above, then pick your driver from the
94 list below.
95
96 Persistent DMA buffers
97 CONFIG_SOUND_DMAP
98 Linux can often have problems allocating DMA buffers for ISA sound
99 cards on machines with more than 16MB of RAM. This is because ISA
100 DMA buffers must exist below the 16MB boundary and it is quite
101 possible that a large enough free block in this region cannot be
102 found after the machine has been running for a while. If you say Y
103 here the DMA buffers (64Kb) will be allocated at boot time and kept
104 until the shutdown. This option is only useful if you said Y to
105 "OSS sound modules", above. If you said M to "OSS sound modules"
106 then you can get the persistent DMA buffer functionality by passing
107 the command-line argument "dmabuf=1" to the sound.o module.
108
109 Say y here for PAS16.
110
111 ProAudioSpectrum 16 support
112 CONFIG_SOUND_PAS
113 Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio
114 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have
115 some other card made by Media Vision or Logitech since they are not
116 PAS16 compatible.
117 If you compile the driver into the kernel, you have to add
118 "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2>
119 to the kernel command line.
120
121 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support
122 CONFIG_SOUND_SB
123 Answer Y if you have an original Sound Blaster card made by Creative
124 Labs or a 100% hardware compatible clone (like the Thunderboard or
125 SM Games). For an unknown card you may answer Y if the card claims
126 to be Sound Blaster-compatible. The PAS16 has 8-bit Soundblaster
127 support, so you can answer Y here for it.
128
129 Please read the file Documentation/sound/Soundblaster.
130
131 If you compile the driver into the kernel and don't want to use isapnp,
132 you have to add "sb=<io>,<irq>,<dma>,<dma2>" to the kernel command line.
133
134 You can say M here to compile this driver as a module; the module is
135 called sb.o.
136
137 FM Synthesizer (YM3812/OPL-3) support
138 CONFIG_SOUND_YM3812
139 Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
140 Answering Y is usually a safe and recommended choice, however some
141 cards may have software (TSR) FM emulation. Enabling FM support with
142 these cards may cause trouble (I don't currently know of any such
143 cards, however).
144 Please read the file Documentation/sound/OPL3 if your card has an
145 OPL3 chip.
146 If you compile the driver into the kernel, you have to add
147 "opl3=<io>" to the kernel command line.
148
149 If you compile your drivers into the kernel, you MUST configure
150 OPL3 support as a module for PAS16 support to work properly.
151 You can then get OPL3 functionality by issuing the command:
152 insmod opl3
153 In addition, you must either add the following line to
154 /etc/modules.conf:
155 options opl3 io=0x388
156 or else add the following line to /etc/lilo.conf:
157 opl3=0x388
158
159
160 EXAMPLES
161 ===================================================================
162 To use the PAS16 in my computer I have enabled the following sound
163 configuration options:
164
165 CONFIG_SOUND=y
166 CONFIG_SOUND_OSS=y
167 CONFIG_SOUND_TRACEINIT=y
168 CONFIG_SOUND_DMAP=y
169 CONFIG_SOUND_PAS=y
170 CONFIG_SOUND_SB=y
171 CONFIG_SOUND_YM3812=m
172
173 I have also included the following append line in /etc/lilo.conf:
174 append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388"
175
176 The io address of 0x388 is default configuration on the PAS16. The
177 irq of 10 and dma of 3 may not match your installation. The above
178 configuration enables PAS16, 8-bit Soundblaster and OPL3
179 functionality. If Soundblaster functionality is not desired, the
180 following line would be appropriate:
181 append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388"
182
183 If sound is built totally modular, the above options may be
184 specified in /etc/modules.conf for pas2.o, sb.o and opl3.o
185 respectively.
