I recently moved for college, and want to play my Xbox but dont feel like lugging my 50in plasma with me. So, I bought an HDMI - DVI cable that I can play my xbox on my pc monitor with the flick of a switch. However, I'm confused on how to get sound. The back of my monitor has a 3.5mm jack, but apart from VGA, DVI and AC that's all. I don't have a sound card in my PC, just what's on the motherboard.
So, how can I go about getting audio? (I also dont have speakers, just headphones straight into the PC)
