Left Channel Headphone Volume Control (Address: 0000010)
BIT D8 D7 D6 D5 D4 D3 D2 D1 D0
Function LRS LZC LHV6 LHV5 LHV4 LHV3 LHV2 LHV1 LHV0
Default 0 1 1 1 1 1 0 0 1
LRS Left/right headphone channel simultaneous volume/mute update
Simultaneous update 0 = Disabled 1 = Enabled
LZC Left-channel zero-cross detect
Zero-cross detect 0 = Off 1 = On
LHV[6:0] Left Headphone volume control (1111001 = 0 dB default)
1111111 = +6 dB, 79 steps between +6 dB and −73 dB (mute), 0110000 = −73 dB (mute),
any thing below 0110000 does nothing − you are still muted
