Realtek HD audio noise suppression

So I've heard from my friends that the noise suppression feature on the Realtek HD Audio is what keeps auto-adjusting to make it so I'm not too loud or whatever. This is rather annoying since I can't make a loud sneeze without practically being muted. So, when I try to turn it off now, the buttons are grayed out and stuck on. I recall before that I used to be able to mess with them, but now they're permanently stuck on. How can I un-gray the button so I can finally turn if off and see if it'll fix my problem?

you can try to reinstall the newest driver to see if this helps. you can get the newest drivers HERE
