I just installed the HW-Q90R and at first everything was fine. I have the sound bar connected on Arc on both sides (soundbar & TV) and I have an apple TV connected to the soundbar. When I switch apple tv to my cable box, the channel on the soundbar switches automatically from HDMI 1 to Arc, but when I want to go from watching from my cabl box, back to the Apple TV, the channel on the soundbar stays on ARC and does not switch to HDMI 1 on its own. How can i get the channel to change automatically again?
