When I first bought my TV, I hooked up my older Sony Blu-Ray/Home Theater system, a 4K Apple TV, and Charter Cable Box. Everything recognized correctly and worked flawlessly for a year and a half. The TV recognized my Home Theater System correctly via HDMI.
A few days ago, it suddenly stopped recognizing it as a home theater system and only as a Blu-Ray player which has messed up the sound and volume control for my entire set-up. It also stopped recognizing my Apple TV correctly. It now thinks the Apple TV is a DirectTV cable box for some reason.
I've tried to manually override the Blu-Ray connection to get it to be a Home Theater again, with no luck. I've successfully changed the Apple TV to recognize it. I've tried unplugging all connections and switching out all HDMI cords.
The only solution I've found is to try using an Optical Cord, but that doesn't work well to control sound since the remote has to point at the Home Theater box which I have hidden.
