Libxenkoaudio.so not working with arm64-v8a

Hi, I get a DllNotFoundException in AudioLayer.Init(). I think the error originates from here:

D/Mono ( 3009): DllImport error loading library ‘libxenkoaudio.so’: 'dlopen failed: cannot locate symbol “_Unwind_SetGR”

Works without issues with armeabi-v7a builds.

Is this a known limitation or can it be fixed to work with 64bit builds?
Thanks!
