Microphone inutilisable (n10/ich 7)

Bonjour.
Comme l’indique le titre, je ne parviens pas à utiliser le micro de mon netbook (principalement pour mumble en fait). Le son fonctionne pour ce qui est d’émettre, je n’ai aucun souci de ce côté… (et il me semble bien avoir mis tous les canaux de son au max)

Je tourne sous une debian 64b, avec des paquets d’un peu tous les dépôts (stable juste pour emesene, et experimental juste pour xfce4.8 ) , mais principalement testing, si je ne me suis pas planté dans mon ‘preferences’.

$uname -a
Linux debian 2.6.38-2-amd64

J’espère que la solution vous sautera aux yeux :slightly_smiling:

PS: J’ai utilisé la balise code pour les sorties de commande, mais s’il y a une balise qui permet le repli du texte ça m’intéresse… sinon le post devient vite long…

PPS: J’ai mis la sortie de dmidecode car demandé dans le “a lire avant de poster” mais si quelqu’un peut m’expliquer comment lire tout ça et quelles informations il est possible d’en tirer, je suis preneur…

Je ne vois la dedans que des entrées audio externes (mic et line), pas de mic intégré.

Bizarre, j’ai pourtant un micro intégré (au moins le trou qui lui correspond à côté de la webcam)…

Ca ne marche d’ailleurs pas non plus avec un micro externe.
D’un autre côté (je ne suis pas du tout habitué aux machines qui tiennent sur les genoux, je précise) peut-être qu’il s’agit de la même ligne entre le jack d’entrée et le micro? J’imagine que l’insertion d’un micro coupe le micro intégré sur les portables et netbooks.

Bon, j’ai réinstallé tous les paquets de ma distrib en testing, pour voir.
Résultat, mon micro externe semble être fonctionnel, puisqu’en mettant du gain, j’entend… de l’écho en infini, et si j’étouffe le micro, ça cesse.

Par contre, je trouve bizarre que la carte maintenant installée soit (selon le mixer d’xfce4.6) : Realtek ALC269VB (OSS MIXER) alors que le lspci m’indique une intel :confused:

Au moins j’ai un résultat, je suppose que je peux l’améliorer, reste à trouver comment…

J’ai réussi à avoir du résultat en ayant suivi la procédure de modif du fichier alsa-base.conf décrite ici: help.ubuntu.com/community/HdaIntelSoundHowto

En tout cas, ça semble marcher, le reste sera du réglage, je suppose que j’y arriverai seul.
Merci de ton aide.
