Hi, My X900E will not play sound through the Dennon receiver. I have the HDMI cable connected to HDMI 3/Arc on the TV, and HD out/Arc on the receiver. The receiver plays sound from the other devices (Cable, PS4) that are connected to it, if the corresponding input is selected on the receiver. However, the receiver does not play sound when I try to watch movies through the Smart TV apps built into the x900e such as Netflix. The sound from Netflix comes from tv, rather than the receiver. How do I set this up so the receiver also sounds on the smart TV apps?
