Audio Recording Problem

Now I've never seen this anywhere else on line which is why I am asking here. For some reason whenever I try to record video the audio is kind of odd. I've used CamStudio and Camtasia and both are the same with this glitch.

I guess the best way to describe it is that the audio goes up and down at times and then it acts fuzzy. I don't know if it's my soundcard or what. It's just I'd like to get this fixed.

Welcome
Go back with system restore and see if that helps
if not
Go to device manager make sure driver is up to date and now yellow warning markers are shown.
