I’ve had this tv for years and I stopped following this thread regularly a while back so I’m not sure if this has already been posted, but I figured I’d come back and share something I figured out for my ARC issues.
I don’t know if it’s the tv or my receiver (Onkyo TX-NR717), but ARC never worked seamlessly. I have input 4 of my mini connect connected to my receiver. When using the built in tv apps, my typical workaround to make ARC work was to start an app, switch my receiver to TV, unplug the receiver and plug it back in. Annoying but effective.
Since my receiver doesn’t pass HDR, I plugged my PS4 into HDMI 1 of my mini connect to play a game. I realized that whenever I switch to HDMI 1, ARC works perfectly with no receiver unplugging required. So, receiver connected to HDMI 4, but using HDMI 1 to watch apps with ARC. I don’t quite understand why this works, but maybe it will work for others. Sorry if this has already been posted.
TL;DR: Connect receiver to HDMI 4, then switch to HDMI 1 to use apps w/ARC.
