ok, that's not good to run wine as root. It was just to be sure it's not a problem of user mismatch. Anyway, I have the same problem stating jack as normal user and then winecfg: no jack option available... very strange. I checked 10 times: libwine-jack is correctly installed (check with dpkg -l | grep libwine , check the winejack.drv.so existance in /usr/lib/wine/) is there a way to see why wine doesn't load that file?
