Thank you Matthew!
I’ve tried your collect audio logs tool but unfortunately it seems to give me a
BSOD. I also tried it with a brand new VM and the latest sysvad example
unaltered (aside from an OutputDebugString call - the apo works fine) and I had
the same result. To reproduce this, I press Y both times, after the first Y
simply playing an audio file before pressing enter. The script seems to crash
when running ddodiag and the BSOD has a stop code: KMODE EXCEPTION NOT HANDLED,
pointing to tabletaudiosample.sys failing - so I assume there’s an unhandled
kernel mode exception. I am running windows 10 pro 1909 through Hyper-V. I
haven’t run the HLK yet but can have a go at it.
On another note, how can I completely uninstall the sysvad example from the
computer? I’ve tried devcon uninstall Root/Sysvad_ComponentizedAudioSample
(which I understand would not remove extension and apo), device manager
uninstall (& delete), and also pnputil /uninstall -d for the extension, apo and
audiosample .infs but there always seem to be remnants in the registry (for
instance the APO GUIDs are still there ie in
MMDevices/Audio/Render/{uuid}/FxProperties and a few other areas).
Many thanks
Joey

Can you take some audio logs of a failed attempt to load your APO and share
them?

Have you run the APO tests in the HLK?

Subject: [EXTERNAL] [wdmaudiodev] APOs not loading by audiodg.exe
Hey guys,
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?
Many thanks
