Pause a channel
#include <sys/asoundlib.h> int snd_pcm_channel_pause ( snd_pcm_t *pcm, int channel );
libasound.so
Use the -l asound option to qcc to link against this library.
The snd_pcm_channel_pause() function pauses a channel by calling snd_pcm_capture_pause() or snd_pcm_playback_pause(), depending on the value of channel.
Unlike draining or flushing, this preserves all data that has not yet been received or played out within the audio driver, to be retrieved or played out after resuming.
This function can return other negative errno values.
