My wife and I tried to watch a movie today from hooking the computer up to my 55" HDTV with a hdmi cable. The picture was great but I had to use the speakers from the computer to play the sound. My HDTV is hooked up to a surround sound system but no sound came thrugh the hdmi cable to the tv to play it. I have a EVGA GTX560 Ti GFX card, is there some thing else I need to hook up to get sound from the hdmi or will I just have to live with it the way it is? Thank you for your time and help.
