Dear Kaj, thanks for Your help. I've installed the lowlatency kernel and I've also reinstalled qjackctl and pd, from the ubuntu repositorys. But I still do have the problem, that I don't hear any sound. I opened Your patch signal-example and I can see the "cables". But I can't hear any sound! I don't have the option "compute" audio. When I click DSP, nothing happens. Shall I install a newer or older version from source?
does any other Jack enabled application produce any sound? You could try something like amsynth, qsynth or hydrogen just to test, if it is problem with Pd or your Jack configuration.
Best regards, Thomas
