I think that the problem is PulseAudio. When I try to start jack i really need to shutdoen every program using the server (pulseaudio is a kind of a server) so that jack has control over the sound card. Only after running jack and starting the server, you can open Puredata and then select in media the jack out/in and connect it in qjackctrl. I tested it with Pd vanilla, but I think it will be the same with pd-extended, since is the same audio engine.
Remember that need to close all software that uses audio, including firefox etc..... 2009/11/14 Hans-Christoph Steiner <[email protected]> > > How would we make Pd use that ALSA compatibility layer?
