Yes, I'm on the KK266.. and the damn non-wdm'ed cmedia drivers.. I can't seem to get to play sounds on more then one thing.. I get the device is in use errors.. But when I run the wdm drivers I can run 2 things at once just fine. I've heard that the norm drivers you should be able to play more then one thing at once as well, but I can't seem to get it to work. Gimme some info as to how you did it and what not so I can try and get this fixed.. k thanks
