Can you take some audio logs of a failed attempt to load your APO and share
Have you run the APO tests in the HLK?

Subject: [EXTERNAL] [wdmaudiodev] APOs not loading by audiodg.exe
I’m working on integration of a proprietary algorithm into an APO, by modifying
the official SYSVAD example. I initially started with writing a basic example -
a channel swapper in the proprietary dsp library being used by the algorithm.
This works completely fine and I’m working with the actual algorithm now. For
strange reasons it seems that the apo has stopped being loaded by audiodg.exe -
no debugger messages being printed in dbgview - even those within APO
initialise. There are also no error messages printed when attaching WinDbg to
the audiodg.exe process. What’s also strange is that the previous channel
swapper example has stopped working as well. I have hardware offloading
disabled, and audio enhancements enabled in the speaker properties. My testing
environment is Windows 10 running in Hyper-V, test mode is on.
Does anyone have any suggestions on what could be happening?
