It turns out that if I attach the APO as an LFX (on windows 10) it works.
The driver is a WinRT driver but built for compatibility with Windows 7.
I was under the impression that SFX, MFX and EFX are the only APOs
available in Windows 10 and not LFX and GFX.
Do you know that properties of the driver determines this?

No, it should just work.

*Subject:* [wdmaudiodev] MFX APO on 7.1 endpoint
I am working on a PortCls driver for a 7.1 audio device. We have an
existing working APO that we have modified to support 7.1 audio. I am
registering the APO via the driver INF - business as usual - but it never
gets loaded when playing audio.
Any special registration required for this type of endpoint?
