   10   The Master Volume Control (MVC) provides gain or attenuation to a digital
   11   signal path. It can be used in input or output signal path for per-stream
   12   volume control or it can be used as master volume control. The MVC block
   13   has one input and one output. The input digital stream can be mono or
   14   multi-channel (up to 7.1 channels) stream. An independent mute control is
   15   also included in the MVC block.
