trying to add back an audio device

I was having problems with an audio device yesterday. In my attempts to get it working, I tried to disable it and then I was going to reenable it. However after disabling it, it completely disappeared from my list of audio devices. So I can no longer use it. How do I add it back?

Thanks. That was really easy. I don't know why I couldn't figure it out myself.

You, Fred, are my Hero!
Ive specially made an account here to tell you this :)

Thanks!

Fred you are the man, you have no idea how much i have searched and pulled my hair out. Praise to the man named Fred!

Yeah, thanks Fred! this is so simple, yet helped me a bunch today :)
