Well, I'm an idiot.
I'm using vista. While trying to get my new headset to work I right click on the sound icon and clicked "Playback devices". I then disabled my sound card (or something) so that I could only hear my headphones.
Now, when I took my headphones out there is a red X by my sound icon, and my sound doesn't work. I haven't been able to figure out how to enable my sound card back, and I'm hoping I'm just an idiot and it isn't some long complicated process.
Any help?
