So I'm buying a pretty sweet sound system off my step brother for my computer. It connects from the amplifier to my computer via hdmi. The only HDMI ports I have on my computer are the mini hdmi's on my 480s. How would I go about outputting sound through my VGAs?
Nvidia video cards are not designed for audio in mind with their HDMI ports. You are better off using a sound card. Only ATI 5000 series properly takes advantage of HDMI audio.
