So, you need to have rt rights. Follow the info in this webpage

You will need to add your use to an audio group and give to that group
RT privileges.

But...................
I can't however not connect as a "client" to the Jack server
with Jack
as "user", only as "root". The error message points on that
Jack can't
connect as a client. And this last line (not in red color):
/(<unknown>:13353): Gtk-WARNING **: Theme directory
scalable/animations
of theme Ny_hjalle has no size field/
hjalle=me/user. I don't get the error message as root, *and I
dont know
if it is a big error*. If I somehow have made a strange user
"Ny_hjalle" for the sound server, in what config file can i
find it?
(I cant find Ny_hjalle in my user settings)
Must I make a Jack user group with "user rights " or....what?
9,10 sounds better than 9.04 however on my laptop.....but
only as root:)

Tommy, it's not the last error message that should be looked at,
but rather the first error message. If you can't determine which
error message is first, copy and paste the entire output of the
messages windown on an attempted jack start (not using root). If
it's a huge output (may be if you have verbose messages turned
on) you may want to paste it in a pastebin like
http://pastebin.ubuntu.com then post the link here.

This is a Ubuntu 9,10 64 bit installtion with Ubuntu Studio 64 bit
package and rt kernel installed with Synaptik. So /Elliott
Barcikowski/ guess that I don't have the right to use realtime
kernel as user, only as root is probably right .So the problem
isn't Jack.

*Solved*, it's working now as user.
With this:
/sudo su -c 'echo @audio - rtprio 99 >> /etc/security/limits.conf'
sudo su -c 'echo @audio - nice -10 >> /etc/security/limits.conf'
sudo su -c 'echo @audio - memlock unlimited >> /etc/security/limits.conf'
I was already us'er for audio.
