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?
