Bonjour,
Je n’ai pas de son, et j’ai lu qu’il pouvait y avoir un tas de raisons à cela, toutes dépendant des distribs/matériels/pilotes…
Je suis débutant et j’ai bien du mal à m’y retrouver dans tout ces termes techniques et ces multiples commandes dont le rôle n’est pas toujours très clair, et leurs sorties un peu obscures.
Je ne demande pas du tout cuit ni du prémaché, me proposeriez vous un lien, ou avez vous des conseils ?
Merci d’avance. 
Pour les grands curieux/courageux (que j’aime ! 
), voilà toutes les infos techniques en ma possessions :
- Je n’ai pas de son quand je lis quoique ce soit (.avi, .mp3) avec vlc
- Je n’ai jamais entendu un seul son sur debian, mais sur Windows aucune anomalie (mon matériel n’est donc pas HS)
Distrib : Debian Squeeze Stable.
