Don't use ARC. Use an optical connection from the tv digital out. Arc is a pain in the ass.

Your problem is probably that you've disabled hdmi control. It has to be on for arc to theoretically work. But when you turn the system on, it will always take over and override your selected input.

That said, I recently used arc because a customer broke the optical jack on his tv. So far it seems to work for him, but I haven't slept for a week.


Oh I just saw you said 50'. No way that will work reliably. I wouldn't ever try it on anything longer than 6'
