Those don’t seem to support WDM-KS, and your error was there …

Could you please try those: https://github.com/adfernandes/precompiled-portaudio-windows?

I don’t want to disable WDM-KS in the pre-packaged DLLs, because on some (most?) systems it works fine and as I understand it’s one of the more professional (i.e. low latency) backends.
