SAPO GFX

Good Afternoon!

First, Sorry for my English.

I’m trying to create a SAPO GFX. I began my work, compiling the example sysfx who came in as an example WINDDK.

The compilation and installation proceeded without problem, but to perform the tests I realized that it is not working.

Documentation for the audio buffer must pass the method CSwapAPOGFX: APOProcess (…), but for debug, it does not

is calling in no time.

By research carried out on the internet, must change the sysfx.inf then I changed the code snippet below by placing

the ID of my audio hardware:

[MfgModelSection.NTx86]
%HdAudioFunctionDriver.CMedia9880.DeviceDesc%=HDAudio.SysFx,HDAUDIO\FUNC_01&VEN_10EC&DEV_0888&SUBSYS_14627379

[MfgModelSection.NTia64]
%HdAudioFunctionDriver.CMedia9880.DeviceDesc%=HDAudio.SysFx,HDAUDIO\FUNC_01&VEN_10EC&DEV_0888&SUBSYS_14627379

[MfgModelSection.NTamd64]
%HdAudioFunctionDriver.CMedia9880.DeviceDesc%=HDAudio.SysFx,HDAUDIO\FUNC_01&VEN_10EC&DEV_0888&SUBSYS_14627379

Still did not work. Could anyone help me in installing A properly SAPO GFX?
I need to know what I should change in sysfx.inf

Thank you all.
