d2-common:  Fix Camcorder Audio

Under 10.2 we are using the Speaker DMIC Stereo settings not
Camcorder Tx.   This finally brings audio up to where we can
hear what was recorded.

d2-common : lower camcorder audio volume

Lowering the setting to 87% puts the volume slightly louder then TW.
83-85% is on par w/ TW but voices seem to come through better at 87%
