Forum Linux.mandriva pas de son dans enemy territory sous mandrake 10.0 official

Salut tout le monde

J'ai un ami qui a une mandrake 10.0 official sur son PC, et qui veut jouer à enemy territory, installé depuis PLF.
Malheureusement y'a pas de son !
J'ai tout essayé : pas moyen
C'est pas un pb du à arts (sur mon PC, quand arts emmerde, il bloque le chargement du jeu, là rien !)
Le son marche dans d'autres jeux comme frozen-bubble...
Donc qu'est-ce-qui ne va pas ???
Voici les messages de la console au lancement du jeu :
