Ce décalage du son c'est un vrai problème. Chez moi il est proportionnel à la durée de la capture.
Essaie de capturer avec VirtualDub 1.7.6, MediaPlayerClassic 6.4.9.0, et AmCAP.
Les drivers de base de ta carte d'acquisition suffisent, pas besoin d'installer une énorme suite.
Et aussi ferme tous les autres programmes (antivirus) et services, voilà un batch pour fermer tous les services :
