I am trying my 65in Samsung Smart TV to recognize my Home Theater Pioneer Reciever connected to HDMI 3 ARC port but no luck. I choose Universal Remote in Settings and go throught the process which
gives up after three attempts. The TV is connected to the CBL/SAT port on the receiver with ARC enabled. It plays back the sound from the TV but the Receiver appears as HDMI 3 "Unkown" device on the TV.
