My unity project includes an unmanaged dll that links to portaudio dll which I've built, everything is configured and built for x86_x64 architecture. My unmanaged dll uses portaudio to open an ASIO audio stream. I want to build it as Universal Windows Build.

The problem is: a standalone build of unity project works properly on windows 10, also Unity editor works fine, but when I build a Universal Windows Build I get a working application but without sound at all. Logs show that portaudio opens stream successfully and gets all properties of the ASIO driver, which in my case is ASIO4ALL, however when I call PaAsio_ShowControlPanel() it opens ASIO4ALL's settings window, but shows that it sees no hardware devices at all, as opposed to listing them when running the same method in a standalone build.

I tried enabling mic permission in unity, visual studio and windows settings. I also tried running everything as admin, did not work.

Debug output I got when building the generated visual studio 2019 solution included those lines: Exception thrown at 0x00007FFDD17BD759 (KernelBase.dll) in MyApp.exe WinRT originate error - 0x80004005 'The window has already been destroyed.'.
