What do you see if you run the audio effects discovery sample on your private
APO?

Greetings list,
I'm trying to modify EqualizerAPO to switch audio processing based on the mode
(to apply rnnoise for "Communications" category mostly) and am stuck with a
problem: APO always gets a "Default" mode within `APOInitSystemEffects2`[1]
regardless of application (Discord, Telegram, Browsers).
Is there anything to be done besides implementing `IAudioSystemEffects2` and
setting `PKEY_SFX_ProcessingModes_Supported_For_Streaming`[2] registry key to
accepted modes (I set all of available)?
Or maybe I completely missed something from the docs and SwapAPO[3] sample?
