Before when I ran jack from qjackctl the RT flag was enabled. The user is/was part of the audio group. It must be some thing to do with the way qjackctrl is running the daemon. as i said earlier sudo is not essential but running from terminal is.
Eitherway I can continue working with this patch which is a big relief. the distribution is 64studio kernel - 2.6.21 64bit RT

$ groups username
the printed list should contain 'audio'. if not, do:
sudo adduser username audio
also, if you're not part of the audio group and therefore don't have realtime privileges, you shouldn't see the 'RT' sign in qjackctl. if you're seeing 'RT' in qjackctl, then you shouldn't have clicks. can you confirm all of that?
in recent linux' systems, there shouldn't be a need to do realtime audio as root.
