LMMS Settings, then Audio Settings, choose PortAudio as your Audio Interface. Then, in the settings for PortAudio, choose ASIO as your backend and you should have FlexASIO as a choice for Device. Set Buffer to whatever works best for your PC and then ASIO should just work! Depending on PC hardware?.

Find your LMMS install folder (Usually in ProgramFiles, and rename libportaudio.dll to libportaudio_default.dll to keep it as a backup. Then, copy in your downloaded libportaudio64bit-asio.dll (for example) to the LMMS install folder and rename it to libportaudio.dll. Now when you go to LMMS -->

Ok FlexASIO is installed now, but LMMS still doesn't recognise FlexASIO at this point, even if you substitute in the portaudio.dll file included with FlexASIO into LMMS install folder. To get ASIO to show up, download 32 or 64 bit libportaudio-asio.dll from github.com/spatialaudio... , then -->

Once PC is restarted, open FlexASIO GUI and setup as follows. Backend: Windows WASAPI, Buffer Size: 1024 (Good starting point), Input Device: None, Output Device: (Pick your main), Input Latency: 0.0, Output Latency: 0.0. Should look like this, may need setup tweaking? Then Save to Default.

(Again, this works for me, but take with a grain of salt and always make your own decisions). First up install FlexASIO from github.com/dechamps/Fle... , then install github.com/flipswitchin... , both with their respective release installers. After this, restart PC I think lol.

even the office pc back where I worked for a bit, same thing .. like am I cursed or am I actively killing them without realising

cos they all start just just black screening and screaming over and over no blue screen error code, no actually usable information in system logs nothing. whyyyyyyyyyyyy :{

ah I can taste it in my brain :( I miss being able to lay down on the floor...
