Bonjour à tous,
J'ai un petit souci dont je viens seulement de me rendre compte puisque
la plupart du temps je mets la sourdine sur mon portable (Acer Aspire
3620) : je n'ai plus de son.
Tout fonctionnait correctement la dernière fois que j'ai eu besoin de
lire des vidéos sur le portable, mais entre temps j'ai eu des soucis
d'arrêt brutal de l'ordinateur et peut-être que la panne est à
rechercher par là... j'avour que si en tant qu'utilisatrice je me suis
bien faite à ubuntu, dès qu'il s'agit d'installer (utrement qu'avec
synaptic) ou de dépanner je ne me sens pas du tout à l'aise (alors que
sous windows oui) parce que je n'ai plus mes repères habituels... c'est
pourquoi je sollicite votre aide.

3 ) Je suis allée faire un tour dans Système > Préférences > Sons
Tous les périphériques (événements sonore etc.) sont sur Alsa...
Le hic, c'est que je ne sais pas quoi faire de ces infos maintenant (et
elles ne sont peut-être pas suffisantes et / ou pertinentes pour aider à
me dépanner !)...
Est-ce que quelqu'un pourrait me pointer dans la bonne direction ?
Merci !
Sandrine
