Eu fiz uma nova instalação do Linux Mint 14.1 x64 no meu Alienware M14x. Tudo estava funcionando bem depois de instalado. Infelizmente, o som é perdido depois de algum tempo. Não há som ao reproduzir vídeo via VLC, no YouTube, etc. Eu tenho que reiniciar meu PC a cada vez para poder ter o som de volta.
Veja algumas informações:
