UGRENT - Messed UP Audio drivers!

So today I wanted to try the new battlefield beta but in order to do so I needed to update my drivers, I eventually was able to and had no issues but then I realized my mic wasn't working.

I updated the whole list of drivers, including HDMI audio drivers.


I can hear sound perfectly clear but my mic won't pick anything up. I've tried using a different jack too.

How do I revert my audio drivers?!
