Instructions on using audio on a FreeBSD 2.1 (or 2.0-current) system.
|
|
See also /sys/i386/conf/LINT.
|
|
|
|
To enable sound driver support, the controller sound code must be included
|
|
in your config file:
|
|
|
|
# SB = SoundBlaster; PAS = ProAudioSpectrum; GUS = Gravis UltraSound
|
|
# Controls all sound devices
|
|
controller snd0
|
|
|
|
Uncomment one or more of these device entries, depending on what type of
|
|
sound card you have:
|
|
|
|
# ProAudioSpectrum PCM and Midi - for PAS
|
|
#device pas0 at isa? port 0x388 irq 10 drq 6 vector pasintr
|
|
|
|
# SoundBlaster DSP driver - for SB, SB Pro, SB16, PAS(emulating SB)
|
|
#device sb0 at isa? port 0x220 irq 7 drq 1 vector sbintr
|
|
|
|
# SoundBlaster 16 DSP driver - for SB16 - requires sb0 device
|
|
#device sbxvi0 at isa? drq 5
|
|
|
|
# SoundBlaster 16 MIDI - for SB16 - requires sb0 device
|
|
#device sbmidi0 at isa? port 0x300
|
|
|
|
# Gravis UltraSound - for GUS, GUS16, GUSMAX
|
|
# For cards that use 2 DMA Channels:
|
|
# drq = Write DMA Channel, flags = Read DMA Channel
|
|
#device gus0 at isa? port 0x220 irq 11 drq 1 flags 0x3 vector gusintr
|
|
|
|
# Gravis UltraSound 16 bit option - for GUS16 - requires gus0
|
|
#device gusxvi0 at isa? port 0x530 irq 7 drq 3 vector adintr
|
|
|
|
# MS Sound System (AD1848 Based Boards)
|
|
#device mss0 at isa? port 0x530 irq 10 drq 1 vector adintr
|
|
|
|
# Yamaha OPL-2/OPL-3 FM - for SB, SB Pro, SB16, PAS
|
|
#device opl0 at isa? port 0x388
|
|
|
|
# MPU-401 - for MPU-401 standalone card
|
|
#device mpu0 at isa? port 0x330 irq 6 drq 0
|
|
|
|
# 6850 UART Midi
|
|
#device uart0 at isa? port 0x330 irq 5 vector "m6850intr"

You may add one or more of the following depending on what you do and don't
|
|
want compiled into your kernel. Note: Excluding things with EXCLUDE_...
|
|
is NOT recommended unless you really know what you're doing.
|
|
|
|
#options EXCLUDE_AUDIO # NO digital audio support
|
|
#options EXCLUDE_SEQUENCER # NO sequencer support
|
|
#options EXCLUDE_MIDI # NO MIDI support whatsoever
|
|
#options EXCLUDE_SBPRO # EXCLUDE SB Pro support
|
|
#options EXCLUDE_SB_EMULATION # NO PAS SB emulation support
|
|
#options EXCLUDE_GUS_IODETECT # NO GUS io detection
|
|
#options EXCLUDE_PRO_MIDI # NO PAS MIDI support
|
|
|
|
Other Options:
|
|
|
|
#options SYMPHONY_PAS
|
|
Adds some code to make pas work with Symphony chipsets. Only use
|
|
this if your pas doesn't work and you have a Symphony chipset.
|
|
|
|
#options BROKEN_BUS_CLOCK
|
|
Some systems with the OPTI chipset and a PAS will require you to
|
|
use this option. Symptoms are that you will hear a lot of clicking and
|
|
popping sounds, like a geiger counter, coming out of the PAS even when
|
|
it is not playing anything.
|
|
|
|
#options MOZART_PORT
|
|
Adds support for Mozart (OAK OTI-601). (Part of the MSS driver)
|
|
|
|
#options OPTI_MAD16_PORT
|
|
Adds support for the OPTI MAD16 Chip. (Part of the MSS driver)
|
|
If your soundcard has a chip labeled "OPTi 82C929" then try this.
|
|
|
|
#options __SGNXPRO__
|
|
Adds support for the SG NX Pro mixer. (Part of the SB driver)
|
|
|
|
#options JAZZ16
|
|
Adds support for the MV Jazz16 (ProSonic etc). (Part of the SB Driver)
|
|
|
|
#options SM_WAVE
|
|
Adds support for the SoundMan Wave (Part of the SB Driver)
|
|
Note: You will need to do some work to get this to work.
|
|
See i386/isa/sound/configure.c
|
|
|
|
#options SM_GAMES
|
|
Adds support for the Logitech SoundMan Games (Part of the SB Driver)
|
|
|
|
#options PAS_JOYSTICK_ENABLE
|
|
Enables the gameport on the ProAudio Spectrum
|
|
|
|
NOTE: The MPU-401 driver may or may not work, and is unfortunately
|
|
unverifiable since no one I know has one. If you can test this,
|
|
please let me know! Also note that you will have to change these
|
|
settings if your soundcard is set for a non-standard address or IRQ.
|
|
Please check your documentation (or verify with any provided DOS utilities
|
|
that may have come with your card) and set the IRQ or address fields
|
|
accordingly.
|
|
|
|
|
|
Also: You can configure more then one card on a single DMA using
|
|
the conflicts keyword in your configuration file. This is useful for boards
|
|
with more then one type of emulation.
|
|
|
|
|
|
Probing problems: Since the SB16 uses the same IRQ and addresses for
|
|
the different drivers, some of the snd drivers will not be probed because
|
|
the kernel thinks there is a conflict. This can be worked-around by
|
|
using the "conflicts" keyword on the sb16's device line.
