Ok this blu ray craze has got me hook up, so I decided to buy a ps3 today. However, my tv only has dvi inputs. So I bought a hdmi to dvi cable so I can have better pictures. I understand that dvi doesn't carry sound, but what do I need to get the sound? My friend have bought some kind of wire that only allow his tv to have audio. I was wondering is there any way I can get sound from my receivers to my surround sound instead of just the tv.
