Why doesn't surround sound work with my new Plasma TV?

Episode 1056 (2:12:53)

Matthew from Wrightwood, CA

Matt just bought a new Samsung Plasma 3D TV with surround sound. The TV isn't working with the surround sound, though. Leo says Matt has to have the ARC Audio return channel. It'll be designated on the side of the TV, and it may not be on HDMI input 1. It probably is input 2. He doesn't really need a special cable, he just needs to enable it. He should look for ARC on the TV itself. Another way is to connect the speakers with optical cables.
