Forum Linux.mandriva Probleme Son Sub + Frontal, et Sortie Optique

Bonjour a tous,

Voila je debute depuis un mois sur Mandriva 2007, et je viens de me rendre compte que mon sub (caisson de basse) + mon enceinte frontale ne fonctionne pas. Seulement les latéraux et satellites. Le tout etant branché en ce moment via des cables audio (non sortie optique celle ci ne fonctionnant pas non plus). Sous Xp tout fonctionne parfaitement, cela ne vient donc pas du matériel. Le "must" serait biensur que cela puisse fonctionner via la fibre optique, pour une excellente qualité.

Alors voila qqs temps que je googelise, et je vois a tout bout de champ cette fameuse commande alsaconf (en root), qui ne repond pas chez moi...

Voici les Infos interresantes sur ma config:

Carte Mere EPoX, si le modele exact est necessaire, me demander, je regarderai sous Xp avec Aida.
