5
6  nn30	read registers nn, where nn = 00 - 09 for mixer settings
7		                              0a - 13 for channel volumes
8  mm31	write the volume setting in pairs, where mm = (nn - 10) / 2
9  rr32	write the mixer settings in pairs, where rr = nn/2
10  xx33	reset all settings to default
11  0y34	select mono source, y=0 = left, y=1 = right
