GMR[2:0]: Gain Level Control for PG6 (Gain Amplifier for Analog Input or R-Channel Bypass)
GML[2:0]: Gain Level Control for PG5 (Gain Amplifier for Analog Input or L-Channel Bypass)
Default value: 111
These bits are used for setting the gain level of the analog source to the mixing amplifier. It is recommended to
set the gain level to avoid saturation in the analog mixer.
