I have no idea what's causing the problem. I already opened the case to check the connections, but damned if I can find an audio wire coming out of the DVD player and going into the motherboard. Just a power cable and an IDE cable.

It wasn't always like this. The only thing I can think of that I did that may have something to do with it is a week or so ago, I had a massive ripping session where I spent about 3 hours ripping all my CDs to my hard drive.
Any ideas? I really want to watch this fucking movie! :icon33:
