I'm working on an audio project that requires the microphone gain to remain constant.

However, by default, Ubuntu seems to use some sort of dynamic microphone gain adjuster, so if the microphone registers a volume that's too loud, it reduces the gain.

This is breaking my project, because if a sudden loud sound occurs, Ubuntu reduces the gain to a point where the audio afterwards is too quiet for my application to hear.

I think the Sound Settings application itself is what's doing the dynamic gain adjustment. I've found if I just open it, set the volume gain to 100%, and then close it before it has a change to adjust, my application runs fine. It's only a problem when I leave Sound Settings open that it screws up the gain.
