Arghh... How many hours have I spent researching this? I have a Samsung LN52B750. I have a TWC cable box Explorer 8640 and JVC TH-G31. The surround sound works with a DVD in the JVC receiver but I can't get the TV to use surround sound. The cable box and JVC unit have separate HDMI cables to the tv. I used a digital optical cable from the JVC unit to the TWC box. How do I get the surround sound to play on the tv? So frustrated..and out $50 on cables and wires. Please help. I'm ready to call the Geek Squad and that is so not me.
