Description of problem: There is no pulseaudio-module-jack in Fedora 8. This has been reenabled in Rawhide, but not F8. This is all the more annoying because JACK doesn't work with PA's ALSA plugin because JACK's ALSA backend requires mmap. As a result, there is no way to start JACK without suspending PA. Version-Release number of selected component (if applicable): pulseaudio-0.9.7-0.17.svn20071017.fc8
Actually, _starting_ them both is not the problem, JACK has a "dummy" driver, but getting them to both actually output sound is.
Getting JACK to output to PA is still a major PITA, but here's how to: - in qjackctl, configure JACK for the dummy sound device and start it - in pacmd, load-module module-jack-source - in qjackctl, connect your JACK application to the PulseAudio JACK Source - in a terminal, run: parec -d jack_in | pacat (Is there really no better way to echo a source to a sink in PA?) - enjoy the half-second latency ;-)
