Name

via_chan_set_speed --  Set PCM sample rate for given channel

Synopsis

Arguments

card

Private info for specified board

chan

Description

Helper function for the SNDCTL_DSP_SPEED ioctl. OSS semantics demand that all audio operations halt (if they are not already halted) when the SNDCTL_DSP_SPEED is given.

This function halts all audio operations for the given channel chan, and then calls via_set_rate to set the audio hardware to the new rate.
