Our driver is not an APO, so is it enough to implement the audio signal
processing modes interface and report that we support
AUDIO_SIGNALPROCESSINGMODE_RAW? Will that cover the *Effects list contains
an enhancements of type Other *failure?

Windows 8.1 created an “audio effects discovery” feature apps can use to
query what audio effects are active.
Windows figures out the answer to the app’s query by asking the driver and
the APO via new calls.
For drivers that don’t implement these calls, Windows has no way of
knowing what effects the driver adds, so it reports “Other” to the app.
So this is the test’s (rather cute) way of saying “hey, you need to
implement the audio effects discovery feature.”
Since your driver does not add any effects, you should implement the audio
signal processing modes interface, and report that you support a signal
processing mode – AUDIO_SIGNALPROCESSINGMODE_RAW.
If your driver includes APOs, you will also need to implement
IAudioSystemEffects2::GetEffectsList and return the appropriate list of
effects; if this changes, set the event handle that Windows gives you.

(Manual) - Certification test
Hi,
My driver is a virtual sound driver based on wavecyclic. I am running
tests on windows 10 RTM using the latest HLK software (v10.0.26624.0) and
the latest HLK filters. I am getting failures in Verify Audio
EffectsDiscovery (Manual) - Certification test.

Our audio driver does not implement the interface for audio signal
processing modes and it passed all the tests on win 8. Our driver does not
add any audio effects as well, so I do not understand what does '*Effects
list contains an enhancements of type Other*' mean. It gives the same
error for all the audio effects category. Pls help.
Thanks,
*Warm regards,*
