Input PGA Volume Update
Writing a 1 to this bit will cause all input PGA volumes to be
updated simultaneously (LIN12, LIN34, RIN12 and RIN34)
LIN12 PGA Mute
0 = Disable Mute
1 = Enable Mute
LIN12 PGA Zero Cross Detector
0 = Change gain immediately
1 = Change gain on zero cross only
Reserved - Do Not Change
