The HP_A and HP_B volume levels are independently controlled by the A and B Channel Volume Control
Bytes when this function is disabled. The volume on both HP_A and HP_B are determined by the A Chan-
nel Attenuation and Volume Control Bytes. The B Channel Bytes are ignored when this function is en-
abled.
