The mono differential output for "Line Out" downmixes the stereo audio
from the mixer, instead of just taking the left channel.

Add a route from the "Right Mixer" to "Line Out Source Playback Route"
through the "Mono Differential" path, so DAPM doesn't shut down
everything if the left channel is muted.

		      playback")
