mixing is done before the sound processing: input signals are automatically scaled by
6 dB in order to prevent clipping during adding; after the addition, the 6 dB scaling is
compensated

ML_DEC[7:0]
ADC volume control left. An 8-bit value to program the gain of the decimator for
left and right independently. The ranges are +24 to
63.5 dB and ∞ dB in steps
of 0.5 dB. The default setting is 0 dB (value 00000000), see Table 53.

MR_DEC[7:0]
ADC volume control right. An 8-bit value to program the gain of the decimator
for left and right independently. The ranges are +24 to
63.5 dB and ∞ dB in
steps of 0.5 dB. The default setting is 0 dB (value 00000000), see Table 53.
