If set the gain of the DAC inputs is controlled by the AUX_LEFT and AUX_RIGHT registers, allowing
a stereo balance to be applied.
If set the gain of the DAC inputs to the mixer is increased by 12 dB (see above).
If set the stereo DAC input is muted on the next zero crossing.

Note 23:
The output from the DAC is 1V RMS for a full scale digital input. This can be boosted by 12 dB if enough headroom is available. Clipping may occur if the
analog power supply is insufficient to cater for the required gain.
