Today I turned my computer on and got on AIM. I sent an instant message to someone and my sound seemed to be off. It was making a weird beeping sound. I followed a troubleshooting guide and uninstalled Realtek and reinstalled it. After I reinstalled RealTek my sound worked just fine, but my mic was screwed up. I had the same problem before when I first got my mic, but the only difference now, is when I go to control panel, I can't access the RealTek menu. The icon is gone, no where to be found. I've tried just about everything, was hoping someone could give me some suggestions.
