hi, I'm trying to install a JACK server on Fedora 11. When I open Qjackctl and press play the following error shows:

hi TB0ne, googled and tried stuff for two hours. But I'm new to linux, so... Thanks for the link. Will try it now.

got the JACK server working:

Code:

But the program (Pure Data) where I need it for gives this error:

Code:

error: JACK error: zombified - calling shutdown handler

Probably something wrong with Pure Data, so I will also post it on that form. Thanks for the help.
