I don't get any audio on my Samsung LED. I get video using a mini dvi to HDMI to my samsung and video is fine, ive tried using a 3.5mm to RCA but no sound.. SO i purchased a 3.5mm (6ft Toslink to Mini Toslink Cable), but get no sound. Here is a screenshot for what i tried to toggle on my macbook pro. any idea? for my tv settings there isnt anythign where I can change my sound output. its set at tv speakers. I also see the red light coming out of the jack. It also reads the optical link on my macbook.
