Passthrough x Volume: PASSAVOL (Address 14h) & PASSBVOL (Address 15h)
7.13.1
Passthrough x Volume
Sets the volume/gain of the analog input signal routed to the headphone/line output.
Notes:
1.
This register is ignored when the PASSTHRUx bit (“Passthrough Analog” on page 44) is disabled.
2.
The step size may deviate from 0.5 dB at settings below -40 dB. Code settings 0x95, 0xA1, 0xAD and
0xB9 are not guaranteed to be monotonic.
