LOUT1 and ROUT1 volumes do not update until
a 1 is written to OUT1VU (in reg 52 or 53)
Headphone volume zero cross enable:
1 = Change gain on zero cross only
0 = Change gain immediately
Right headphone output mute:
0 = Normal operation
1 = Mute
Right headphone output volume:
000000 = -57dB
...
111001 = 0dB
