O microfone parou de ser detectado

Question

Eu não tenho ideia de como ou por que isso aconteceu. A parte de vídeo da webcam funciona, mas não o microfone que costumava funcionar antes.

O microfone funciona no Windows, apenas parou de funcionar no Ubuntu 12.10.

A webcam é uma LifeCam VX-5500.

Aqui estão alguns arquivos de log por enquanto:

Answer 1

Desinstalar todos os kernels sudo apt-get purge linux-image-* e usar um Live CD para executar o boot-repair corrigiu meu problema.
