Problème de réglage du son

Mon problèmes est un peu inhabituelle, de manière ou mes cartes son fonctionne et que quand je fais les testes des baffles cela fonctionne parfaitement (j'ai un 5.1, les 5 baffles sonnes bien durant les testes les uns après les autres). Mais le soucis survient quand je lance un programme comme un jeu ou un programmes similaire à Windows média player. Mon son fonctionne alors que en stéréo à plus de 5.1 !!!

Au début, je pensais à un bug dans les drivers, mais je les ai réinstaller et après avoir pas mal chipoté, j'ai changer de carte son, mais là encore les baffles durant les testes fonctionnes parfaitement, mais pas durant tous les autres programmes...

La musique et les jeux sa passe encore, mais regarder un DVD en stéréo alors que tu devrais le regarder en 5.1 est plutôt frustrant...
Je constat donc que même en changeants de carte son le problèmes persistes et je ne sais donc pas comment résoudre mon problèmes.

Merci de votre aide, si vous trouver une solution...

test sous directX ?
