[PATCH v2 4/4] ALSA: usb-audio: Operate UAC3 Power Domains in PCM callbacks

2018-07-30 Thread Jorge Sanjuan
Make use of UAC3 Power Domains associated to an Audio Streaming path within the PCM's logic. This means, when there is no audio being transferred (pcm is closed), the host will set the Power Domain associated to that substream to state D1. When audio is being transferred (from hw_params onwards), t
