Deux microphones répertoriés dans la section d'entrée de Pulseaudio, "Microphone interne" et "Microphone" mais le problème est que

Étant sur un ordinateur portable, (Acer Aspire V3-571G pour être spécifique) Ubuntu 13.04, la sélection du port "Microphone interne", tout le bruit joué dans le microphone me revient via les haut-parleurs. Étant sur l'unité, je ne peux pas contrôler les ports que j'utilise sans ouvrir manuellement le contrôle du volume audio Pulse, et c'est pénible. La sélection du port "Microphone" utilise le micro interne et externe chaque fois que l'un est branché et n'a pas ce problème. Je n'ai plus d'idées sur ce qu'il faut faire.
