Just got my 1st hdtv....(yes I know I'm late)....I had it set up that I could play my ps2 or xbox 360 and the sound would come out of tv and stereo. I have multiply game systems so I have a switch box. I used to have the sound run through the switch box to my stereo....but know I only have sound from my Tv...will someone please tell me...(exactly what I need) and how to hook it up...Thank you
