Use the -l asound option to qcc to link against this library.
The snd_pcm_capture_pause() function pauses a channel that's capturing. Unlike draining or flushing, this preserves all data that has not yet been received within the audio driver, to be retrieved after resuming.
This function can return other negative errno values.
