volume control is not supported. A request to the master volume is stalled and ignored. The built-in digital mute
controller can be manipulated by audio class specific request. A master mute control request is acceptable. A
request to an individual channel is stalled and ignored.
Interface #1
Interface #1 is the audio streaming data-out interface. Interface #1 has the following seven alternative settings.
