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.
Right click the speaker icon in your system tray. Then, click playback devices. Highlight your nvidia HDMI audio device, and click the "set default" button. When movie is over, set back to computer speakers the same way. I had to do this last week with my new 560 ti's. Have fun kiddo.
