Got a logitech C260 webcam (using windows 7 home premium.) The built-in mic (on the webcam) sounds better on recordings than the laptop mic... or even an external mic for the built-in jack. It has no background noise, and just a nicer quality sound. However, the webcam mic always has an echoing sound coming from my speakers, even when the webcam itself is not in use. The mic is so sensitive that it picks up the sound of my keystrokes as I'm typing this message. When I disconnect my external speakers from the laptop, then I get feedback if I talk to loud (or actually when I talk normal!) So it's better to have the speakers pluggen in.
Two questions... how can I get the mic to turn off when the cam turns off? And more importantly, how can I stop the echoing sound when I'm actually using the webcam on skype or recordings?
