Hello,

I have a TerraTec Aureon 5.1 Fun sound card. Divers are v5.12.1.639, signed
by Microsoft (and installed during Vista rc2 installation).

I have configured the speakers in 5.1 surround with the Speaker Setup
pannel. Then I launched the test and all speaker work well. When i clic on a
speaker picture, the sound comes from the good speaker.
But my problem is that even the good configuration, all sound on windows,
mp3 playing with wmp11, DVD watching with wmp11 or gaming with game designed
for 5.1 surround sound.... i always got a stereo sound with only my 2 front
speaker (front left and front right). After testing almost all application
with sound, i never got 5.1 sound, only in sound configuration pannel.

I'm disposed to give any other information to help to fix this issue.

Some informations from dxdiag :

I Would Say that you use the windows XP Drivers beacause The Windows
Vista Drivers Don't Support 5.1 for some uknown reason
