Hello! Did somebody try to install AC97 WDK sample instead of a standard Microsoft AC97 driver? I tried to install it in VirtualBox 2.0.4, the sample driver was successfully loaded and got hardware resources but does not play or record. Driver generated debug messages "CIV out of range" and audio position doesn't move. Since standard MS AC97 driver works fine in VBox, I think that hardware emulation is correct.
