I go to Volume Control -> Options -> Properties -> Mixer device: Realtek HD Audio Input and the volume slider for the "Recording" tab keeps going down gradually whenever I'm in a Skype call or anything that I'm using the mic to talk. Does anybody know how to fix this? I pull the slider back up, and it just slides back down until it gets to right below the very bottom. This only happens when I'm using the mic, it stays put when I'm not. The result is everyone in the Skype call hears my voice as very feint. Does anyone know how to fix this? Any help would be appreciated, thanks!
