Hello everybody, I looked at the sound card (like many others) bought for my laptop and the 5.1 sound from my Teufel Concept E 400 zukitzeln out, but it should not be. The card has only driven the Satelite, unfortunately not the subwoofer. In addition, the quality of the satellite was not the best. Since no drivers are available - I'll send the card back with Sincerely.
