I forgot to precise that my sound card is a Presonus Firebox and run with Freebob.<br>
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%.<br>
It is a bit strange because I got the rtirq script congiured for my firewire card. So it should not work better than my firewire ...<br>
<br>
I am a bit lost !! :O[<br>

Is the 'real' cpu time (e.g. from top) also that high? It could be that there is a bug in the time reporting of the freebob backend, resulting in a bad calculation of the cpu time.<br>

Pieter</blockquote><div><br><br>Hi,<br>It is very strange. I can't see a real correlation between cpu load displayed by htop and the DSP load displayed by qjackctl.<br>In htop the cpu is quite unstable too, but it doesn'tt change at the same time as the dsp load in qjackctl. Perhaps it is due to a latency. but I can't say if is linked.<br>
I have made some more test :<br><br>1- runing qjackctl with freebob backend : both dsp load (qjackctl) and cpu load (htop) are unstable but not really linked.<br>2- runing qjackctl with alsa backend : dsp load is quite stable but cpu load is unstable.<br>
3- running jackdmp in a console with Freebob then alsa : cpu load is unstable.<br>4- when jackdmp or qjackctl are killed : cpu load is normal around 2% and stable.<br><br>So :<br>Is it normal that the cpu load displayed in htop is unstable ? <br>
If it is, then as you said pieter, could it be a bug with freebob ??? I never saw this before, on the same laptop but with 32bits OS.<br>Is there a problem in my kernel config ?<br>Is there a something wrong with jack or freebob with the 64bits arch ?<br>
<br><br>Well, if someone as some idea for me to make more tests ... I would be happy ;)<br></div><br></div>Mysth-R<br clear="all"><br>-- <br>* ***************************************************************************************<br>
