We have the JWM22 receiver below the tv in the living room of our 2024 340RL. I am trying to get it to play tv sound (Insignia). In my TVs at home just hook up an HDMI cable to the ARC port on the tv then to the HDMI In port on the receiver & make sure the ARC port is activated on the tv. That is what the instructions say in the JWM22 manual as well yet I can’t get tv sound from the receiver speakers. There was an HDMI cable already plugged into the ARC port on the tv which is fed into a channel behind the tv. I’m not sure where it goes or if it plugs into the HDMI out port of the receiver but there are no other devices for it to plug into. I tried a number of things in the tv settings but nothing has helped so far. Anyone else tried this & if so can you tell me what I might try? Thanks
