[LAU] debugging conflicts Pulseaudio/Jack

Hi I've chosen the option 3 (route PulseAudio to JACK while JACK is running) of this guide: http://jackaudio.org/pulseaudio_and_jack BTW, http://trac.jackaudio.org/ is down since yesterday. It used to work fine in the past but I'm having an issue just after using Stretchplayer (and therefore jack). I'm on Debian testing (Gnome 3.4.2). I can't see anymore the audio applet. In Settings»Audio I see that there's no output device. The applications that are trying to use Pulseaudio are listed but of course no sound is produced. jackd is not running. pulseaudio-module-jack is installed and my ~/.pulse/default.pa contains the following lines: load-module module-native-protocol-unix load-module module-jack-sink channels=2 load-module module-jack-source channels=2 load-module module-null-sink load-module module-stream-restore load-module module-rescue-streams load-module module-always-sink load-module module-suspend-on-idle set-default-sink jack_out set-default-source jack_in How can I debug this problem? Thanks in advance -- Federico
