STA308A
When ZCE = 0, volume updates occur immediately. Each channel also contains an
individual channel volume bypass. If a particular channel has volume bypassed via the
CnVBP = 1 register then only the channel volume setting for that particular channel affects
the volume setting, the master volume setting will not affect that channel. Each channel also
contains a channel mute. If CnM = 1 a soft mute is performed on that channel.
