There's a snippet on MSDN 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
