I tried hooking up my macbook to my TV. So I figure I hook it up (displayport to DVI). I have a cable that does DVI to HDMI. Ok so the picture works. Then I plug The audio cable (from the headphone jack) into the back of the TV. No sound! Turns out that is only for PC input using the VGA connector. Without having to go through a receiver, how do you get sound to the TV? I guess it either expects toslink from receiver or sound to come though HDMI.
