встроенная веб-камера и микрофон не работают (12.02 и 14.04)

Сегодня почему-то я понял, что моя веб-камера и микрофон больше не работают, я решил обновиться до 14.04 (используя это как оправдание и предполагая, что после него проблема исчезнет). К сожалению, ничего не случилось.

Как ни странно, ноутбук, похоже, не распознает ни веб-камеру, ни микрофон. Однако * аудиовыход работает отлично.
