I have a Samsung Flat screen TV, andI want to hook up and stereo system using RCA audio plugs. But my TV's audio output doesn't work. And I went to the TV menu and it's not allowing me to activate the TV's audio output. Where it says, "Audio Video Output" it says this: ----- And I have my aaudio connections from the TV to the stereo input, and the stereo system is on, but no response from the TV. TV only plays sounds from the TV speakers.
