Windows 7 - Win 7 Ult 64 Audio worked, and now it doesn't?

Hello everyone, first post here.

I am a college student with a computer that I built myself. I currently run a Gigabyte EP45T-UD3LR MoBo which has the capability to run 5.1 surround sound (maybe better?) and has some other neat things that I enjoy. I installed Windows 7 Ultimate x64 a month or so ago and everything was working fine until I went home last weekend for Thanksgiving Break.

I unplugged my logitec surround sound system, packed up my computer, and drove home. When I setup my computer at my house I wanted to listen to some music but I did not have my speakers, so I plugged in my 5.1 headset. After I plugged this in I got a pop-up asking about my "new audio device" or something, basically a configuration pop-up. I clicked through quickly as I have never had to actually setup the audio before, and sure enough my audio stopped working... kind of.

For those who are familiar with gaming, I was on Ventrilo (voice chat program) and could not hear anyone even though my mixer showed that there was audio occurring. However, I could still hear youtube videos and things like that from Google Chrome. I didn't pay much attention to this and I just got back to my fraternity today, plugged in my surround sound and now my audio is completely non-existent.

I've updated all of the drivers, I've messed around with the settings, I searched high and low and nothing anyone else did seemed to help. My card and speakers are being recognized, they just aren't working.

Any help would be monumentally appreciated!

Did you try the System Restore? That would have been the first thing I would have tried.
