NAME

via_chan_set_fmt - Set PCM sample size for given channel

SYNOPSIS

"SYNOPSIS"

int via_chan_set_fmt (struct via_info * card, struct via_channel * chan, int val);

ARGUMENTS

card: Private info for specified board
chan: Channel whose sample size will be adjusted
val: New sample size, use the AFMT_xxx constants

DESCRIPTION

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.

This function halts all audio operations for the given channel chan, and then calls via_chan_pcm_fmt to set the audio hardware to the new sample size, either 8-bit or 16-bit.
