I forgot to precise that my sound card is a Presonus Firebox and run with

Freebob.

I got the idea to test with my U-control Uca202 (Behringer) Usb sound-card,

and there is no problems. The cpu percent is quite stable around 2,1%.

It is a bit strange because I got the rtirq script congiured for my firewir=

e

card. So it should not work better than my firewire ...


I am a bit lost !!  :O[

Hi, and thank you for your answer.I am actually trying qjackctl 0.2=

.23 and the problem is the same. So it should not be a QT problem.Anywa=

y, I can note that for the same qjackctl config the cpu load percent is low=

er on version 0.2.23  (~=3D 2.5 - 3%) than on the 0.3.2 version (3 - 4=

.5%).


If someone has anonther Idea ... :)Cheers,Mysth-R2008/4/5, Russell Hanaghan <hanaghan@starband.net>:


Sounds similar to the issue I spoke of here a=

 week ago.If its the latest Qjackctl built with QT4, its a QT4 p=

roblem of yetto be defined origin. Only difference I had, going =

by your description, was that


My CPU was running at 99% and staying there.=

If you run jack from the command line and see normal Cpu, thiswo=

uld point to the same problem.I have not yeilded =

a root cause from my Googling. Only some 


similar instances from other users, not only with Qjackctl & Qsynt=

h,but also Skype and others built with QT4.=

My fix for now was to revert to an older version of qjackctl.


Thanks!On Apr 5, =
