My logitech wireless headset just suddenly stopped working on me. I restarted the computer, and now it wont play any sound even though it is on. It does work when i plug it into a different computer though, so this leads me to believe that it is windows that is causing the problem. I can also plug a regular old el cheapo set of headphones into the jack on the back of the computer, and that works fine. Think this could be some kind of weird driver issue?
