I think you should post the whole INF file.
Can you see open the device from a Win32 app using waveInOpen()?

Subject: [wdmaudiodev] HD Audio problem
Hello..
I'm writing audio driver and have some problems.
My INF interface section:
[SndDev.Interfaces]
AddInterface=%KSCATEGORY_AUDIO%,%KSNAME_Wave%,SndDev.InWave
AddInterface=%KSCATEGORY_RENDER%,%KSNAME_Wave%,SndDev.InWave
AddInterface=%KSCATEGORY_CAPTURE%,%KSNAME_Wave%,SndDev.InWave
AddInterface=%KSCATEGORY_AUDIO%,%KSNAME_Topology%,SndDev.InTopo
AddInterface=%KSCATEGORY_TOPOLOGY%,%KSNAME_Topology%,SndDev.InTopo
[SndDev.InWave]
AddReg=SndDev.InWave.AddReg
[SndDev.InWave.AddReg]
HKR,,FriendlyName,,%SndDev.Wave.szPname%
HKR,,CLSID,,%Proxy.CLSID%
[SndDev.InTopo]
AddReg=SndDev.InTopo.AddReg
[SndDev.InTopo.AddReg]
HKR,,FriendlyName,,%SndDev.Topo.szPname%
HKR,,CLSID,,%Proxy.CLSID%
...
And so on... I work with MSVAD DDK sample and HD Audio modem, but I want to
install sound
driver over this modem. It is strange, I know.. :)
I registered interface for device in AddDevice function via
IoRegisterDeviceInterface call. It's
started successful.
But I can not open handle for interface via CreateFile call. GetLastError
return code 5 (Access is denied).
KS Studio failed when I try instantiate Wave or Topology from
KSCATEGORY_AUDIO category.
The main headache is incorrect audio device work. My driver installed
correctly (no errors during
installiation and in Device Manager all is Ok), but I can not select it for
play or record sound.
What do you advice to me?
Thanks
