I have a HP G60 running 32bit Vista Premium. The tv is a 32" Toshiba HDTV. The video works perfectly the sound will only come through the computer. I updated the NVIDIA drivers and even when I switch the sound to HDMI it changes nothing. The only thing it does is make any video on Firefox not have sound on both computer and tv. I also tried using a DVD to see if it would work with something not on the net and it did not.
