Probleme son micro

Bonjour,

J'ai un probleme de son :

En communication avec un correspondant sur n'importe quel outil (TS, MSN, Steam,...), je m'entend, mon correspondant s'entend et m'entend, parfois trés fort eco.... , seulement je ne l'entend pas, j'ai regardé partout, je en vois pas. Bizard.

Voila mon DX Diag (en partie), sachez que le correspondant et en XP.

Merci d'avance.
