Thank you. That was exactly what was required. I found the right device in one of the drop-down lists on a driver properties pane. So, what does the Swap APO example do? I noticed that the device has changed from the generic "Microsoft HD Audio Driver" or similar to a "CMedia with Swap APO". But I can't find a property page that implements the PropPageExt.dll. How is the property pane invoked? And what does the sample do? Thanks, Roger. --- Leonard Shoell <lshoell@xxxxxxxxxxxxxxxxx> wrote: > I install the sample by going to the device manager, right-clicking on the > audio device, selecting "Update Driver" then selecting the options that > allow you to point the directory that has the INF and DLL files. > > Make sure you first change the "VEN_434D&DEV_4980" in the following line in > the INF to the audio device in your system. > > %HdAudioFunctionDriver.CMedia9880.DeviceDesc%=HDAudio.SysFx,HDAUDIO\FUNC_01& > VEN_434D&DEV_4980 > > Leonard ____________________________________________________ Do you Yahoo!?
