.SH NAME
via_chan_set_fmt \- Set PCM sample size for given channel
.SH SYNOPSIS
.sp
\fB
.sp
int via_chan_set_fmt  (struct via_info * \fIcard\fB, struct via_channel * \fIchan\fB, int \fIval\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIcard\fB\fR
Private info for specified board
.TP
\fB\fIchan\fB\fR
Channel whose sample size will be adjusted
.TP
\fB\fIval\fB\fR
New sample size, use the AFMT_xxx constants
.SH "DESCRIPTION"
.PP
Helper function for the SNDCTL_DSP_SETFMT ioctl.  OSS semantics
demand that all audio operations halt (if they are not already
halted) when the SNDCTL_DSP_SETFMT 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 the new sample size, either 8-bit or 16-bit.
.SH "ABOUT THIS DOCUMENT"
.PP
This documentation was generated with kernel version 2.6.0.
