Pb son Linux

C'est quoi comme carte son?
Ubuntu la trouve-t'il?

Merci de votre réponse..
Je suis un peu novice sous linux (installé depuis 3,4 jours)... Je pense que ma carte doit être une Intel car en tapant la commande lsmod voici ce qu'il me sort (les paquets commencant par snd concernent le son nan?)
