Sound stopped working after downloading driver

I downloaded a webcam driver and now my sound won't work. It says it's running and music is running, even the speaker's sound test will work, but nothing comes out except during the speaker test. I went to my sound options and the "realtek digital output" bar is moving and all, but that sound test won't work.

I also deleted the driver and restarted the computer. Still no sound. Help

Oh, also, there's no start up sound like there used to be either and I'm sure everything is still plugged in properly. It only stopped after I used to webcam on msn after downloading the driver. I think the computer thinks there is a mic on or something. I've tried adjusting all the settings and disabling it. Still nothing.

Ummmmmmm you deleted the drivers? WHich drivers? The sound (realtek) drivers or the webcam drivers? I lack the knowledge to help you but that is important info for those who can.

The webcam drivers.
