Internal microphone mute by itself

[Pauline]

whenever i start to run the webcam, the internal mic will be turned off to mute by itself. i've tried all kind of setting and configuration but couldn't help. does anyone have any idea? is it the driver program problem or have to deal with system registry?
the computer is Toshiba Satellite A200-AH5
using Vista Home premium SP1
Thanks!

Try keeping up with the Vista service pack updates. Vista is up to Service Pack 2 and you are probably missing other critical updates as well
