Bonjour à tous. 
 
Lecteur regulier des journaux du site, je me pose aujourd'hui sur mon clavier car depuis quelque temps un problème auquel je ne trouve pas de réponse m'agace serieusement. 
 
Je m'explique : 
Je possede un carte son Sound blaster live 24! (chipset CA0106). 
J'ai eu quelques petit souci au début pour pouvoir en faire sortir du son, mais après desactivation des sorties numériques, tout est rentré dans l'ordre. 
Le problème qu'il me reste à regler est que le micro ne fonctionne pas. Lorsque je lance alsamixer, aucun controle du micro n'y apparait, ni d'ailleur le nom du chipset. 
 
Voici ce qui s'affiche dans alsamixer: 
Card: CA0106 
Chip: 
View: [Playback] Capture All 
Item: IEC958 [Off] 
 
Et voilà le resultat de amixer -c 0 :
