I have a Hp Envy tablet which I just bought, and the webcam seems to work fine until I call someone in Skype. It then freezes a few seconds in and the light goes out, but keeps my picture frozen, and I can see the other end fine. If I use the tools menu to check my webcam, it keeps my video up fine for a while. When I try to use Skype Video, it won't detect my webcam at all. I've tried updating drivers etc., it says they're all up to date. I've tried a refresh too. Help!
