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.
