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 from Documentation/Configure.help | |
64 | are relevant to configuring the PAS16: | |
65 | ||
66 | Sound card support | |
67 | CONFIG_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 | ||
80 | OSS sound modules | |
81 | CONFIG_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 | ||
88 | Persistent DMA buffers | |
89 | CONFIG_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 | ||
103 | ProAudioSpectrum 16 support | |
104 | CONFIG_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 | ||
115 | FM Synthesizer (YM3812/OPL-3) support | |
116 | CONFIG_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 | ||
138 | EXAMPLES | |
139 | =================================================================== | |
140 | To use the PAS16 in my computer I have enabled the following sound | |
141 | configuration options: | |
142 | ||
143 | CONFIG_SOUND=y | |
144 | CONFIG_SOUND_OSS=y | |
145 | CONFIG_SOUND_TRACEINIT=y | |
146 | CONFIG_SOUND_DMAP=y | |
147 | CONFIG_SOUND_PAS=y | |
148 | CONFIG_SOUND_SB=n | |
149 | CONFIG_SOUND_YM3812=m | |
150 | ||
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" | |
153 | ||
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" | |
160 | ||
161 | If sound is built totally modular, the above options may be | |
162 | specified in /etc/modprobe.conf for pas2, sb and opl3 | |
163 | respectively. |
