+.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.
