Hi. I currently have my 360 connected via component, the picture plugs are in my HDTV but i managed 2 stretch the cable enough to be able to plug in the audio plugs into my stereo hifi (red/white). But i think i might use a HDMI cable for my 360. Only problem is i dont know how to connect it up so that sound will come out the hifi. Its an oldish hifi which only supports the red/white stereo plugs. Is it possible to have picture via HDMI but sound via red/white plugs?
