Bonjour,
Suite à la recompilation de tout mon système pour changer les options de compilation (optimisations moins agressives pour plus de stabilité), j'ai eu quelques soucis, dont le dernier à résister est l'audio.

Alsa est compilé en module avec théoriquement tout ce qu'il faut pour son bon fonctionnement. Je ne crois pas avoir changé grand chose, et le système auparavant fonctionnait bien. C'est au lancement de la machine que j'ai un certain nombre de messages d'erreur liés à Alsa. J'ai regardé dans /var/log/messages, et voici ce que je trouve au sujet de l'audio :

Ce que je vois, c'est le "No bus" qui a l'air d'être un souci... Est-ce que quelqu'un aurait une idée à ce sujet ? Je ne sais pas si les informations postées sont les bonnes...
Merci d'avance !

Salut,

Regarde du côté des paramètres de module. En effet, j'ai eu aussi la même blague et j'ai du réinjecter un fichier alsa dans /etc/modules*trucmachin
