alsa: add host suspend/resume support
Both input and output streams may be in SND_PCM_STATE_SUSPENDED after the host is suspended and resumed, meaning "Hardware is suspended". snd_pcm_readi() and snd_pcm_writei() will return -ESTRPIPE if called while the stream is in this state. Call snd_pcm_resume() to enable audio output and capture after host resume. Signed-off-by: Bjørn Mork <bjorn@mork.no> Signed-off-by: malc <av1474@comtv.ru>
