Same exact problem with Denon

I came here to post this exact problem with my Denon. When I have Anynet+ enabled for ARC (Audio Return Channel) it automatically switches the Denon to the "TV"/ARC input when the tv is switched on, and a variety of other circumstances mentioned before.

I haven't made my way through the entire thread, but it seems the consensus is that we're out of luck? And that the solution is to not use the "feature" and run an additional optical wire (defeating the purpose of ARC)?

Seems like ARC should be separated from CEC, or at least have an option to control it.
