\fR
.SH "ARGUMENTS"
.TP
\fB\fIcard\fB\fR
Private info for specified board
.TP
\fB\fIchan\fB\fR
Channel whose stereo setting will be adjusted

.SH "DESCRIPTION"
.PP
Helper function for the SNDCTL_DSP_CHANNELS and SNDCTL_DSP_STEREO ioctls.  OSS semantics
demand that all audio operations halt (if they are not already
halted) when SNDCTL_DSP_CHANNELS or SNDCTL_DSP_STEREO is given.
.PP
This function halts all audio operations for the given channel
\fIchan\fR, and then calls via_chan_pcm_fmt to set the audio hardware
to enable or disable stereo.
