Hi! Matthew,
   Thanks for the document you provided.    I'll check it.
  I'm still uncertain about the possibility whether componentized extension
driver for sound effect could be acceptable for WHCK. I'll move on and try
it.

  Best Regards.

Hi Matthew:

  Thanks for your guidance, and I found that most AddComponent directives
was put in an extension.inf file.

  Could the extension.inf with the  directive AddComponent in be included
in my driver package? Then I can associate  the APOs to many mainstream
sound cards.

  Is this kind of driver package acceptable by WHCK and get certified?



  Best Regards.

You would author a driver package which was targeted to this hardware ID,
certify it, and put it on Windows Update.

Hi! Tim:

    Thanks for your kind reply.

    The APOs will be installed with a specific hardware, such as HDAudio
device, USB audio device.

    My question is when qualifying the APOs in WHCK, and submitting WLK
signature for catalog file, is the software itself acceptable? Or the APOs
should be associated with a hardware by an IHV(independent hardware vendor)
to be qualified WHCP?

   We are not IHV, don't have any hardware products. We sold only
software, and wanna have our algorithm certified by WHCP.



  Best Regards.

Could the APOs be verified against WHCP alone without any hardware
audio device, and get signed or get a logo?

No,  Officially, APOs are part of a driver and must be associated with a
specific piece of hardware.  You can't install an APO independently or
generically.
