So.. I googled and mroogled and didn't come up with anything real solid, so I'll ask here. My internal microphone keeps changing the input volume by itself. I like to keep it low since the internal mic is very good. I have ambience noise reduction checked as well. I use skype voice chat when I use the internal mic. It's under the audio preference pane that I'm setting the audio input volume. The problem is it keeps going to maximum input volume. BLAH!! Getting very annoying, especially when I'm gaming and on skype, it picks up the fan noise bad. I notice if I keep speaking louder, or make louder noises, the input toggle thing slowly moves toward the maximum end. Why not just stay still??
