Wineasio is for both u can find the 32 and 64bit compilations and inside the makefile in the sources they explain you must specify where is your wine path in the 64 bits compilations in /usr/lib/ or /usr/lib/etcetc../wine/ or correct it and copy the file manually the point of jack is what i am not sure at all, this --mixed ive never heard after i just installed from synaptic, the thing is i can watch the dll inside the library menu in winecfg but not his options in regedit i think that is the point becouse is not registered.
