Hi Derek,
Did you try running as sudo or root?
Of course! Just tried this and yes no clicks!!!
Before I was using qjack ctrl to control jackd. What is strange is that when I run jackd from command line without sudo privileges there are no clicks either !?
So following from that discovery it seems sudo privileges are not necessary to avoid the clicks but avoid the use of or running of qjackctrl under normal privileges to run the jack daemon. I wonder why this is ?
odd - maintaining jack connections between apps will be a headache without the GUI. I suppose I could also start the qjackctrl from command line with sudo privileges ...
thanks Derek, Conor

you can tell qjackctl to start jack with realtime priority

I was running jackd through qjackctrl with realtime priorities. That didn't make a difference.

are you member of the audio group?
$ 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.

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

Assuming you are Ubuntu ... are you using the realtime kernel? In Hardy at least, I get smooth pd audio with realtime jack and dropouts when using the same with the regular kernel. It seems the realtime kernel is *too* agressive for my laptop ... ?

Hi Conor,
a few things:
- I would check every single setting in Qjackctl against the ones you
use in the command line, maybe there's some difference. 2) I would doublecheck how Qjackctl is called (i.e. do you start from commandline or menu bar, and if menu bar then how is it actually being called?) 3) Once jackd has been started you can start Qjackctl and use it to manage connections. It will recognize that the jack engine is already started. 4) Yes, you could sudo qjackctl. You could also make one bash script that starts everything, and sudo that.
best! Derek
