Configuration register H (0x07)
The ZCE bit enables zero-crossing volume adjustments. When volume is adjusted on digital
zero-crossings no clicks will be audible.
Setting the ZDE bit enables the zero-detect automatic mute. The zero-detect circuit looks at
the input data to each processing channel after the channel-mapping block. If any channel
receives 2048 consecutive zero value samples (regardless of fs) then that individual
channel is muted if this function is enabled.
