Analog volume control. A 6-bit value to program the left master volume
attenuation. The range is from +16.5 to 48 and
16.5 dB gain is there to boost the 150 mV (RMS) which comes from for
instance an FM tuner IC to 1 V (RMS) needed to drive the headphone driver
full-swing. Default value 111111, see Table 29.
