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.

Note the 2nd SPDIF input exists only on CMI8738/PCI-6ch versions.
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
