Microphone Base Silence?

[Chev]

So I'm running multiple machines with Linux Lite and all of them we're having issues getting the microphone base silence to remain static; if it gets too loud, it jumps up to try to compensate for it - this is incredibly counterproductive for what we're trying to do. The machines are all generally POS, but they work just well enough for what we want them to do.

We're running 3.2, but I'm not positive if it's Final or not. Does anyone know how to force the Silence base to remain where we want it?
