So, I just got an 82" Samsung QLED tv for Christmas. What should have been a straight swap out of the TV has turned a bit more problematic. My system now: Samsung QN82Q6 Flat 82" QLED 4K UHD 6 Series Smart TV Onkyo HT-S5800 5.1.2-Channel Dolby Atmos Oppo Blue Ray player PS4 AppleTV The previous tv was a Vizio (for what it's worth). Anyhow, I took the HDMI cable from the receiver and plugged it into the HDMI 1 port of the new TV, exactly as it was on the old TV. Everything works as it's supposed to EXCEPT the AT&T uVerse box. For some reason, there is absolutely zero sound being sent to the receiver. I've tried all of the uVerse 'troubleshooting' tools as well as swapping out HDMI cables, swapping ports on the receiver, and still no audio from the uVerse box. Any ideas?
