And there's a more complete .inf from another person attempting a similar thing
here:

Thank you for your prompt response. This is a great news. Is there by any
chance a sample/template of such .inf file?

The recommended approach is to create a driver package which consists of your
APO binary, an .inf which wraps wdma_usb.inf and specifies your hardware IDs,
and (optionally) a Sound control panel UI plugin. Run the HLK tests and submit
to WHQL to get this signed.

Subject: [wdmaudiodev] sAPO for USB audio devices
Hi everyone,
What options do I have to enable my sAPO for USB audio devices? Should I bundle
it with a custom USB audio driver and have them WHQL signed, or there is a
simpler option available? I will need a production grade solution with driver
signature and audiodg protection intact.
Thank you,
Edward
