Terratec Aureon 7.1 sound card will fit in your bin
 

An email to Terratec provided an admission that they knew that the sound card had problems. What's scary is that the card managed to make it onto the shelves at all. These problems are almost certainly driver problems. Even a small amount of testing showed them up. Terratec said that a new driver should be available soon but that doesn't make up for the fact that this card shouldn't go into your system in its current state.
