Volume Control

The volume of the audio signal is controlled by default by an attenuation function in software. This is called when
the audio block is transferred to the transmit buffer prior to transmission to the CODEC for output. Optionally,
the volume can be controlled directly by the CODEC, based on configuration in the source code. See section
5.3.1.3 for further details.
