via_chan_set_stereo

Name

via_chan_set_stereo -- Enable or disable stereo for a DMA channel

Synopsis

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

Arguments

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

Description

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.

This function halts all audio operations for the given channel chan, and then calls via_chan_pcm_fmt to set the audio hardware to enable or disable stereo.
