Well - I don't know if it works. This is what I tried when I was using the wrong Wine-installations to make them work, it failed. The minute I installed Wine-rt - I didn't have to use that command at all (after purging wine-stable and wine-development). BTW the filename is "wineasio.dll.so", but I was able to register it with both full name, just "wineasio.dll" and even just "wineasio" (as long as I gave the full path, or was in the same dir as the wineasio files) - however it never worked
