[résolu]bug alsa à détec auto ...d'une carte son à l'autre ?

[helid]

Bonjour,

Sur une carte mère il y a un processeur sonore qui ne s’initialise pas tout le temps, donc adjonction d’une SB Live. Mais elle a vieilli maintenant et ne s’initialise plus tout le temps non plus …

Comment puis-je régler alsa de manière à ce qu’au démarrage j’ai accès à au moins une des cartes sons (par defaut la live car le son est meilleur et l’autre le reste du temps) de manière automatique ?

[mattotop]

Mais si tu fais ton alsaconf, alsa ne detecte pas les deux cartes ?
Parceque alsa sait gèrer plusieurs cartes en même temps, même s’il faut peut être faire les choses manuellement.
Sinon, tu as essayé de rmmoder le module et de le reinserer, quand ta carte s’est mal initialisée ?
Sinon, alsaconf a des fonctionnalités de scan en ligne de commande, tu peux peut être trouver des infos utilisables dans un script:

Je suis en train de voir tout cela mais comme cela ne se déclenche jamais régulièrement …

Déjà le BIOS avant grub n’affiche pas toujours la ressource de la carte son …

Ensuite je vois que tu es en PnP aussi, je viens de m’y mettre et depuis j’ai tout le temps un son (4 démarrages) … Autant.

Pour le modules, je te dirais …

Trouvé: C’est le pilote alsa qui est buggué: Il a envie de détecter une carte son audigy de “temps en temps” …

Je suis passé avec les pilotes OSS de 4Front, aux moins eux fonctionnent tout le temps.
