Ok, so I have an MSI K8t neo, leadtek 6800 gt, audigy 1 platinum, 1 gig of corsair xms xl, and a 3400+ athlon 64. My headphones are the surround sound zalmans. The other day I was watching a paintball video, and suddenly, my right ear phone goes out. I have un installed/re installed drivers, and that doesnt work. I have tried other headphones, and those only work on the left side as well. I bought these around 3 years ago, or a little more. (the card that is) My headphones are about 6 months old..
