Function
Automatic Volume Correction (AVC) Loudspeaker Channel

bit [11:8]
Note: To reset the internal variables, the AVC should be switched off and then
on again during any channel or source change. For standard applications, the
recommended decay time is 4 sec.
Note: AVC should not be used in any Dolby Prologic mode (with DPL 35xx),
except in PANORAMA or 3D-PANORAMA mode, when only the loudspeaker
output is active.
