have a new Samsung 75" 6350. My reciever is a denon avr-1912.
I have all my cable box and playstation going into the reciever. And one hdmi from receiver to the TV.
Both reciever and the TV support ARC. I have it connected to the arc imports. I want to use hdmi and not have to add additional optical cable.
The audio works for the things I have plugged into the receiver, except for audio coming from the TV (smart apps.) I have the Samsung audio set to "audio out".
What else do I need to do to get this working? Thanks.
