2.15.5 AUDIO - Mixer Output Volume Control Registers (MIX_OUTx_VOL)
These registers manage the output signal volume for the mixer, Left and Right respectively.
The MSB, bit D7, of each register is the mute bit. When this bit is set, the output is silent.
There are 32 gain selections from 0 dB to -46.5 dB. The step size is 1.5 dB.
