CMPCI(4) BSD Kernel Interfaces Manual CMPCI(4) NAME
cmpci -- C-Media CMI8x38 audio device driver SYNOPSIS
cmpci* at pci? dev ? function ? audio* at audiobus? mpu* at cmpci? opl* at cmpci? flags 1 DESCRIPTION
The cmpci device driver supports C-Media CMI8x38 based sound cards. The device has SPDIF input/output interfaces, 16bit CODEC with analog mixer, OPL3 FM Synthesizer, and MPU401 compatible MIDI I/O port inter- face. MIXER DEVICE
The mixer device of cmpci driver can be accessed via mixerctl(1) command. The complex structure is analyzed as follows.

MIXER EXAMPLES
Here are examples about wave playback and SPDIF input/output ports. Playback to speaker, SPDIF input to SPDIF output mixerctl -w playback.mode=dac spdif.output=spdin spdif.monitor=off Playback to SPDIF output, SPDIF input to speaker mixerctl -w playback.mode=spdif spdif.output=playback spdif.output.playback=wave spdif.monitor=spdin SPDIF input to both SPDIF output and speaker mixerctl -w spdif.output=spdin spdif.monitor=spdin Playback to both SPDIF output and speaker mixerctl -w playback.mode=spdif spdif.output=playback spdif.output.playback=wave spdif.monitor=spdout Mix playback and SPDIF input to speaker mixerctl -w playback.mode=dac spdif.monitor=spdin SEE ALSO

The cmpci device driver appeared in NetBSD 1.5. BUGS
4ch/6ch playback is not yet available. Joystick port is not supported. spdif.output.playback=legacy does not seem to work properly. BSD
