the basics of writing a control panel applet. The sample only works in

WDM audio driver sample. The AC97 WDM audio driver sample runs on an Intel<65>

motherboard with integrated AC97 controller, like the Intel 810 Chipset.<o:p></o:p></span></p>

for the device with the one from the floppy. After updating the driver, the
