		# On most (all?) devices with a single / mono speaker an
		# amplifier with a differential input connected between LOUT
		# right and left is used. We deal with this by silencing the
		# right output and mixing left + right to the left output.
		#
		# An alternative approach for devices using the differential
		# setup would be to set bit 15 of register 5 in the codec,
		# which turns the stereo unbalanced line out into a mono
		# balanced line out.
		#
		# This possibility was discovered after we already shipped the
		# current solution and the current solution has the advantage
		# of also working on devices which only use LOUT left in
		# unbalanced mode. The net result is the same for devices using
		# the differential setup, so we just stick with what we have.
