SETTING
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 is the audio streaming data-out interface. Interface #1 has the following seven alternative settings.
Alternative setting #0 is the zero bandwidth setting. All other alternative settings are operational settings.
Interface #2 is the audio streaming data-in the interface. Interface #2 has the following 19 alternative settings.
Alternative setting #0 is the zero bandwidth setting. All other alternative settings are operational settings.
Interface #3 is the interrupt data-in interface. Alternative setting #0 is the only possible setting for interface #3.
Interface #3 constructs the HID consumer control device and reports the following three key statuses.
