I have a Marantz SR5010 and is arc, I can’t get sound form it. The only way is to run my fios box to the AVR, but then my picture is not as good and when watching sports it’s even worse. If I run Fios box to One Connect, picture is much better and hockey is great again. But no sound out of the AVR. I’m stuck
In the tv sound settings have you set to bitstream?
