After hours of searching, and reading, I got it finally to work. I found a specific Libportaudio 32bit File, in some thread on one of those LMMS Forums, and this one seemed to work over the portaudio which in another thread is listed.

I uploaded it, the way it was: https://ufile.io/ifgnc

here. Try it with this. And I installed lmms 1.1.3 from the lmms.io page, and swapped/changed the 32bit one with the one from the directory. Also I installed asio4all, and choosed it. Should work.
