You can read up on the Declarative, Componentized, Hardware Support App (DCH)
design principles here:
DCH Design Principles and Best Practices - Windows drivers | Microsoft
If you were to include an AddComponent directive in your own .inf, then you
would still have to solve the problem of how to get your .inf deployed to the
desired systems in such a way as is compliant with the DCH principles.

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?

What you would do is make up a "software component hardware ID" for your APO.
It would begin with APO\....
An IHV that wanted to use your APO would put an AddComponent line in their .inf
that referenced your APO.

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

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.

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