So I had a problem a little while back where my recording started out fine, then was muffled. I fixed it by changing the audio settings in Windows, but now all of the recording is muffled from the start, and when I try using the Amplify effect, the Okay button is greyed out. I move the slider way over but it doesn’t let me click the button.
Usually it is a [u]Windows Setting[/u]. Audacity just “captures” the audio data it’s getting from Windows and the drivers, and it doesn’t have the ability of applying effects in real-time as you’re recording.
We may need to know more about what you are recording and you hardware setup… Are you using the mic built-into your laptop? A USB mic? Are you recording streaming audio? Etc.?
If you have a directional mic, make sure you are talking into the front. And if it’s a studio style “side address” mic, talk into the front side, not the end. If you are using a studio condenser mic, make sure your audio interface has phantom power turned-on.
It’s possible that your mic has gone-bad but that’s unlikely.

Amplify won’t amplify the peaks over 0dB unless you allow clipping (allow distortion).
Audacity has already pre-scanned the audio, it knows the current peak, and Amplify will default to whatever gain or attenuation is needed to “normalize” the file with “maximized” 0dB peaks. The default should ALWAYS WORK, even if your peaks are already at 0dB and it actually does nothing.
