gain control register location versus mode and ID
Depending on the operational mode and ID of the device, the various gain control registers have locations in
the register map that may change. For example, if the codec is configured as ID 10, it means that the device
will be converting the rear surround DAC data. In this case, the surround DAC volume word written to register
38h is now used to control the master volume control, rather than the normal master volume 02h. In addition,
when the surround volume mute control is written as demute, mute in the DAC PGA register 18h is automatically
overridden. Then the user does not have to make an unexpected additional write to register 18h to demute the
DAC PGA.
