Is this speculation on your part or something that has recently been
confirmed to be the case? AFAIK, there is nothing SoC specific about the
ECANCELED issue, and we also still do not know what is causing the audio
regression.

The thing is, we have a working and well-tested solution in the
user-space service so there is no rush to switch to the in-kernel one
(and risk distros removing the user-space service) before this has been
fixed.
