Salut,

Je n'ai pas de microphone reconnu avec mon chipset (HDA Intel / Realtek ALC882).

Le son fonctionne correctement, mais je n'ai pas d'entrée 'Microphone' dans la section recording de Alsamixer, je n'ai que "Mic boost" et d'autres options incompréhensibles dont je ne peux que les muter ou non (case à cocher dans le gestionnaire de volume).

Cependant, si je mets 'Microphone' dans playback à 100%, le son qui entre dans le microphone ressort par les haut parleurs connectés au PC. Bon signe ?

Je vous prie de m'aider, je n'ai trouvé aucune solution (pourtant, j'ai beaucoup cherché).

Voici plus d'informations :

Je sais pas si le problème à été résolu, mais je n'ai aussi pas de son sur n'importe quel élément branché en jack sur mon pc (même puce audio que la tienne, une hda_intel).

Il semblerai que ce soit le kernel, mais qui sais quand est-ce que ce sera résolu ?
