First I use onboard sound with the MSI K8N Neo2 Platinum and Win XP sp2. I have had this computer for 2 months and has worked flawlessly. Today I bought a Mic to use with Ventrilo, I set up the bind key then clicked "Test" and Ventrilo crashed and froze up. After a manual restart my sound stopped working. When sound should play all I here is the sound very faintly with a loud fuzzy noise. No matter how I change the volume settings in windows it is always the same loudness. Even when I mute through Windows I still here the noise. I have the latest drivers and even tried to reinstall them with no luck. The speakers and head phones work fine as I have tested them with my mp3 player. All help is appreciated.
