.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver supports C-Media CMI8x38 based sound cards.
|
|
.Pp
|
|
The device has
|
|
SPDIF input/output interfaces,
|
|
16bit CODEC with analog mixer,
|
|
OPL3 FM Synthesizer,
|
|
and MPU401 compatible MIDI I/O port interface.
|
|
.Sh MIXER DEVICE
|
|
The mixer device of
|
|
.Nm
|
|
driver can be accessed via
|
|
.Xr mixerctl 1
|
|
command.
|
|
The complex structure is analyzed as follows.
