Hey everyone, im new at this and have just set up my new home theater. Working with a Yamaha RX-V683 receiver. LG OLED 65E7 is the TV. DirecTV, XBox One S all work flawlessly but when i go to watch Netflix or Amazon Prime Video i just hear audio out of the TV only. I have messed with TV settings, tried Optical cable to no avail. The TV is connected to the receiver via ARC. Any other thoughts? I have read through all the search topics but nothing i have found has helped. I figure it has to be something with the receiver at this point.
