.SH "DESCRIPTION"
.PP
Some audio applications want to perform certain mixer operations. Audio drivers can
use this functuon to assign the right mixer device to an audio device.
.PP
Older audio applications written for previous OSS versions still use the mixer interface
to do certain operations such as playback/recording volume control or recording
source selection. OSS 4.0 and later has some new aidio ioctl calls such as
SNDCTL_DSP_SETRECVOL and SNDCTL_DSP_GETRECVOL which do the same more reliably.
New audio drivers should implement these functions in their ioctl entry points.
