Hi..I have recently bought the system Sony DAV-S880. I have a Sony TV with a single Audio out socket. at the back of the dav-s880's receiver, there is a 4 socket(fronr r/l, rear r/l) connector and a 2 socket (front r/l) connector. That means I have 1 for output from my Tv but 2 inputs for the system. How can I entegrate my TV sound to my system?????
