I have a Vizio HD TV with a coaxial audio out. I have a 2.1 speaker system with a powered subwoofer with a 1/8" female socket. Using a Y cable with a 1/8" male end and 2 RCA 3.5 male connectors on the other end. Nothing seems to work. The TV has RCA cable audio in and only the one coaxial audio out.
