I was uninstalling some programs and I wasn't paying attention and I think I uninstalled my audio device. Under "Sounds and Audio Devices" in Control Panel it says I have no audio device. The only sound I can get now is the beeps. I have a Toshiba Satellite laptop with Win XP. I've tried reading other posts and the Help section in Windows and I can't figure out how to get my sound back. Please help!
