Hi David.
I know that it's code is ac97 sample.
In my souce code, I changed some code my audio driver.
And I just want to know,
Why can't CreateFile operate?
hTopology = CreateFile (pDeviceInterfaceDetailData->DevicePath,
//"\\\\?\\PCI#VEN_1102&DEV_0005&SUBSYS_00311102&REV_00#4&35FAE160&0&00F0#{dd
a54a40-1e4c-11d1-a050-405705c10000}\\SpdifOutTopo",
GENERIC_READ, FILE_SHARE_READ|FILE_SHARE_WRITE,
NULL, OPEN_EXISTING, 0, NULL);
=> have error : can't find the file specified.
I checked my registry with winobj tools,
"\\\\?\\PCI#VEN_1102&DEV_0005&SUBSYS_00311102&REV_00#4&35FAE160&0&00F0#{dda5
4a40-1e4c-11d1-a050-405705c10000}\\SpdifOutTopo".

Hi Eric,
I think you need an AC97 codec mounted on a motherboard in order to run this
sample driver directly. All new motherboards are now HD Audio, so they won't
work either. You'll need to find an old motherboard which has AC97 on it.
The creative card is a PCI device, and uses a proprietary chipset, so this
sample driver will not work with it.
Best regards,
David Roach
