I have a Denon receiver, smart TV and a cable box all connected. When I play my television, sound comes through the receiver to the speakers. However, when I use the internet on the smart tv, the sound only comes from the TV and not through the receiver to my speakers. What needs to be connected or a change of connection for the sound to always come through the receiver to the speakers no matter whether I am using the TV or accessing the internet on the TV? Thanks for any help anyone may be able to give!
