So I tried to install some new speakers that turned out to be finnicky, so I decided to just use the one that's already on my monitor. Except I messed with some settings, and now my sound has gone missing. I plugged the chord for the sound where it should be in the back of my computer, but my sound is still missing.

I have tried every setting imaginable in the Realtek HD Audio Manager, but my sound still hasn't come back.

Running Vista 64-bit OS.

Anyone know of anything I can do to fix my sound?
