INPPGAVOLL and INPPGAVOLR volume do
not update until a 1 is written to
INPPGAUPDATE (in reg 45 or 46)
Right channel input PGA zero cross enable:
0=Update gain when gain register changes
1=Update gain on 1
register write.
Mute control for right channel input PGA:
0=Input PGA not muted, normal operation
