Can someone diagnose this JACK error message?

It seems like your missing permissions, does your distro set up an audio
group? Is your user a member of that group?
Which version of JACK do you have installed? JACK2 is preferred, and I believe Debian provides decent configurations. To install JACK2, run this command...
sudo apt-get install jackd2
If you already have jack2 installed, do a reconfigure like this...
sudo dpkg-reconfigure -p high jackd2
If you still are experiencing problems comment, I'll follow up.

OK. I start JACK without starting the JACK server. I get:
23:09:22.730 Patchbay deactivated. 23:09:22.765 Statistics reset. Cannot connect to server socket err = No such file or directory Cannot connect to server socket jack server is not running or cannot be started 23:09:23.059 ALSA connection graph change. 23:09:23.250 ALSA connection change.
Then I press the 'play' button.
I get:

If I press nothing, the above read error message repeats infinitely.
I installed JACK from repositories and this is what I got.

Gilles 'SO- stop being evil' over 13 yearsWhat OS are you doing this on? Where did you get JACK (OS package, compiled it yourself, …)? What exact commands did you run?
-
Matthew over 13 yearsDebian Lenny, from repos. I ran it from the GUI and simply pressed the play button. The same works on the repo version installed on Debian Squeeze several days ago.

redmoskito over 13 yearsI'm having the same problem on Ubuntu 10.10. It worked a few weeks ago; not sure what's changes since then

J. M. Becker about 12 years@redmoskito: Why are you running such an outdated distro? If you are going to go that long before getting the newest release, you should be running the LTS. You might 'technically' be considered 'supported', but by the skin of your teeth. The regular releases are not meant for 'long-term' stability, even though they might seem stable enough. The requirements for inclusion, are drastically different between a 6-month and LTS.
