Hi, No, I think I changed nothing after compiling Jack_fst. But I'm not sure about that, so I'm going to try compiling fst and jack_fst again. I'm running the kernel that comes with Suse 9.2. It's the "2.6.8-24-default" one. I'm running Wine version "20040505" and jack "0.98.1". I think the problems comes not from LSM or rtsools because it crash when I run it as root. I'm sorry, I can't say more about the problem, the terminal show me no errors.
