Qualité du son via Unity et Rhythmbox

Bonjour,

Je rencontre un problème un peu étrange auquel je ne trouve pour le moment pas la solution sur les forums.
Je suis sous Ubuntu 12.04 et utilise un portable ThinkPad T60. Après l'ouverture de session, le son est bon sur youtube ou autre. Si je clique sur l'icône "tableau de bord" ou si je lance Rhythmbox, le son devient tout pourris (craquement permanent et au déplacement de la souris) et le reste jusqu'au redémarrage.

Avez-vous un idée ?

Ci-dessous, le résultat du script alsa-info.sh
