Hi
I'm using the 3538m drivers with windows vista x86. The surround mixer and practically all the stuff Ive tested works well

My only problem is that I can't set the speakers to 5.1 in windows. I get an error saying "Format not supported by device".
So with the help of surround mixer I can upmix stereo things to 5.1, but DVD-s and other things (games, etc) which would have "real" 5.1 can only play in stereo.
So basically I get 2 channels upmixed to 5.1 but can't listen to 5.1 stuff.
Has anyone else encountered this before? And if yes, what did you do to solve it?
