Mic not working in Garry's Mod

[Tia]

I have been using my mic in Garry's Mod for the past few months and all of the sudden, it just quits working. Only a stuttering few of my words are transmitted.
I've tested it in other programs (Portal 2, Audacity, various online tests) and the mic itself is fine, so it's on Garry's Mod's end where the problem is.
I've tried using a different mic in Garry's Mod, same problem.

I am using the Rock Band mic for Xbox.

Did you install any new addons or mods recently?

Nope.

Gmod is pretty small, best bet is to just uninstall it and re-install it. If you have any addons just move the addons folder out of the steam folder and then back in once its installed again.
