Help text

This Audio function is compatible with USB Audio Class specification 2.0. It implements 1 AudioControl interface, 1 AudioStreaming Interface each for USB-OUT and USB-IN. This driver doesn't expect any real Audio codec to be present on the device - the audio streams are simply sinked to and sourced from a virtual ALSA sound card created. The user-space application may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host.
