4 Instructions on using audio on a FreeBSD 2.1 (or 2.0-current) system.
5 See also /sys/i386/conf/LINT.
7 To enable sound driver support, the controller sound code must be included
10 # SB = SoundBlaster; PAS = ProAudioSpectrum; GUS = Gravis UltraSound
11 # Controls all sound devices
14 Uncomment one or more of these device entries, depending on what type of
17 # ProAudioSpectrum PCM and Midi - for PAS
18 #device pas0 at isa? port 0x388 irq 10 drq 6
20 # SoundBlaster DSP driver - for SB, SB Pro, SB16, PAS(emulating SB)
21 #device sb0 at isa? port 0x220 irq 7 drq 1
23 # SoundBlaster 16 DSP driver - for SB16 - requires sb0 device
24 #device sbxvi0 at isa? drq 5
26 # SoundBlaster 16 MIDI - for SB16 - requires sb0 device
27 #device sbmidi0 at isa? port 0x300
29 # Gravis UltraSound - for GUS, GUS16, GUSMAX
30 # For cards that use 2 DMA Channels:
31 # drq = Write DMA Channel, flags = Read DMA Channel
32 #device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3
34 # Gravis UltraSound 16 bit option - for GUS16 - requires gus0
35 #device gusxvi0 at isa? port 0x530 irq 7 drq 3
37 # MS Sound System (AD1848 Based Boards)
38 #device mss0 at isa? port 0x530 irq 10 drq 1
40 # Yamaha OPL-2/OPL-3 FM - for SB, SB Pro, SB16, PAS
41 #device opl0 at isa? port 0x388
43 # MPU-401 - for MPU-401 standalone card
44 #device mpu0 at isa? port 0x330 irq 6 drq 0
47 #device uart0 at isa? port 0x330 irq 5
49 You may add one or more of the following depending on what you do and don't
50 want compiled into your kernel. Note: Excluding things with EXCLUDE_...
51 is NOT recommended unless you really know what you're doing.
53 #options EXCLUDE_AUDIO # NO digital audio support
54 #options EXCLUDE_SEQUENCER # NO sequencer support
55 #options EXCLUDE_MIDI # NO MIDI support whatsoever
56 #options EXCLUDE_SBPRO # EXCLUDE SB Pro support
57 #options EXCLUDE_SB_EMULATION # NO PAS SB emulation support
58 #options EXCLUDE_GUS_IODETECT # NO GUS io detection
59 #options EXCLUDE_PRO_MIDI # NO PAS MIDI support
64 Adds some code to make pas work with Symphony chipsets. Only use
65 this if your pas doesn't work and you have a Symphony chipset.
67 #options BROKEN_BUS_CLOCK
68 Some systems with the OPTI chipset and a PAS will require you to
69 use this option. Symptoms are that you will hear a lot of clicking and
70 popping sounds, like a geiger counter, coming out of the PAS even when
71 it is not playing anything.
74 Adds support for Mozart (OAK OTI-601). (Part of the MSS driver)
76 #options OPTI_MAD16_PORT
77 Adds support for the OPTI MAD16 Chip. (Part of the MSS driver)
78 If your soundcard has a chip labeled "OPTi 82C929" then try this.
81 Adds support for the SG NX Pro mixer. (Part of the SB driver)
84 Adds support for the MV Jazz16 (ProSonic etc). (Part of the SB Driver)
87 Adds support for the SoundMan Wave (Part of the SB Driver)
88 Note: You will need to do some work to get this to work.
89 See i386/isa/sound/configure.c
92 Adds support for the Logitech SoundMan Games (Part of the SB Driver)
94 #options PAS_JOYSTICK_ENABLE
95 Enables the gameport on the ProAudio Spectrum
97 NOTE: The MPU-401 driver may or may not work, and is unfortunately
98 unverifiable since no one I know has one. If you can test this,
99 please let me know! Also note that you will have to change these
100 settings if your soundcard is set for a non-standard address or IRQ.
101 Please check your documentation (or verify with any provided DOS utilities
102 that may have come with your card) and set the IRQ or address fields
106 Also: You can configure more then one card on a single DMA using
107 the conflicts keyword in your configuration file. This is useful for boards
108 with more then one type of emulation.
111 Probing problems: Since the SB16 uses the same IRQ and addresses for
112 the different drivers, some of the snd drivers will not be probed because
113 the kernel thinks there is a conflict. This can be worked-around by
114 using the "conflicts" keyword on the sb16's device line.
