Jackd not working 12.04

[tontis]

Hey,
I recently re-installed ubuntu 12.04 and did this tutorial installing the audiopackages including qjackctl. For some reason qjackctl won't work, and since I'm quite the newbie at this, I have no idea why.
This error code is produced:

20:02:26.955 Patchbay deactivated.

these are screens of my settings in qjackctl.

How much soundcards do you have?
Is it Ubuntu Studio or Ubuntu?
If this is Ubuntu Studio you can set Priority to 89.
Try to kill PulseAudio with

pulseaudio -k

After this try to run Jack.
If all okey and Jack runs correctly then the reason of problem is conflict between Jack and PulseAudio.
It is a command to start PulseAudio

pulseaudio --start

HTry to kill PulseAudio with

pulseaudio -k

After this try to run Jack.
If all okey and Jack runs correctly then the reason of problem is conflict between Jack and PulseAudio.
It is a command to start PulseAudio

pulseaudio --start

This is true only if you have set respawn to "no".

Hey, thx for the replies.

I tried pulseaudio -k

Now jackd seems to start, however there's still some errortext, I'm not sure why, what it does or if it's even important. It's the following:

Cannot connect to server socket err = No such file or directory
Cannot connect to server request channel
jack server is not running or cannot be started

The entire code:

To answer your questions - I have two soundcards but is currently only using one. I am running normal ubuntu with most of the soundpackages from ubuntu studio installed.
