I went on vacation last weekend and everything worked fine. When I came back some of the higher frequency sounds (read: vocals and similar range) are incredibly low and distorted. As well as some distortion in the rest of the range of sound. I've tried adjusting the sound using both the default windows sound options and my audio software that came with my mobo. Also tried using a different codec pack rather than the one I had installed before. All with no changes in the sound. I also tried reinstalling directX. Everything is reset back to default from before I left. Please help! I have no experience dealing with audio problems.
