Sup everybody. I'm having a little bit of a problem hooking up my all in one Hitachi HTD-K320 surround sound system to my Hitachi l32ax03a tv. Here is my set up. I have my xbox hooked up via HDMI to my Tv.......I have my laptop hooked up via HDM to my Tv......then I have my surrond sound hooked up via Rca cables ( from output of my tv to the input of my surround system) My surround sound only has 3 sources (DVD player) (radio) (Line) And I believe line is the surround sound setting for my stereo but im not too sure. And my TV wont recognized the system and i cant set my TV to external audio manually, so some help would be very much appreciated.
