A64 and Audigy 2ZS Problem... (Win x64)

Hello there

I installed an Audigy2 ZS card on my s939 system, and I have found a few
bugs. I installed the x64 drivers and the sound application, but the
latter does not work. Makes me select only a 7.1 speakers setup, and for
example in World Of Warcraft I can't hear the music playing... How come?
I also have the feeling that videos' sound is played a bit slow, like in
slow motion... What does it depend from? Should I install the sw on the
audigy cd anyway?

TIA
