fake_tuner seems to work for me. Thanks!

I take that back. Something funky going on.

This morning, I noticed that not only was "fake_tuner" not working, but right now when I hold the knob-button, it does not switch sources at all, not even to the Aux source. Removing the line "fake_tuner=1" returns it to normal operation so that I can at least toggle to Aux again.
