I checked my drivers, and I found that Microsoft WINMM WDM Audio Compatibility Driver has this message: Device status: A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. When someone signed on or off AIM, my computer would beep. Now that I have removed the driver, it plays the sound. If a window pops up that usually makes a noise, it beeps in my computer AND my speakers... I did a system restore checkpoint before I removed it. How would I get it back? Do I need it back? That's the Microsoft WINMM WDM Audio Compatibility Driver. Any help appriciated.
