I forgot to precise that my sound card is a Presonus Firebox and<br>
run with Freebob.<br>
I got the idea to test with my U-control Uca202 (Behringer) Usb<br>
sound-card, and there is no problems. The cpu percent is quite<br>
stable around 2,1%.<br>
It is a bit strange because I got the rtirq script congiured for<br>
my firewire card. So it should not work better than my firewire ...<br>
<br>
I am a bit lost !! :O[<br>
<br>
<br>
Is the 'real' cpu time (e.g. from top) also that high? It could be<br>
that there is a bug in the time reporting of the freebob backend,<br>
resulting in a bad calculation of the cpu time.<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>

FreeBoB is guaranteed 110% bug-free.</blockquote><div><br><br>héhé :D <br></div><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><span class="q"><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Is there a problem in my kernel config ?<br>
Is there a something wrong with jack or freebob with the 64bits arch ?<br>
</blockquote></span>
It could very well be a 64bit issue somewhere. I haven't tested freebob on 64bit yet.<span class="q"><br>

Well, if someone as some idea for me to make more tests ... I would be happy ;)<br>

It might be interesting if you could figure out exactly what the differences are between your setups. Mainly software versions etc...</blockquote><div><br>well, on the same laptop I got a 32bits openSuse system and a gentoo 64bits in dual boot.<br>
I have tested on OpenSuse, with both Kde3.5 and Fvwm, just using qjackctl 0.3.2 with jackd 0.109 and it works perfectly.<br>Now on my gentoo 64 bits I tryed on both Kde4.0 and Fvwm-crystal, just using qjackctl 0.3.2 and jackdmp0.70. I also tryed with qjackctl 0.2.23 (in case it was due to QT4 library) and jackdmp-svn and jackd 0.109 : in all the case I got the cpu load problem.<br>
<br>Do you think this is a firewire problem ? perhaps I forgot an important option when I compiled my kernel (2.6.24-rt1)<br>I think I will try with another kernel. Will see if there is new kernel available. otherwise I will try with an older (2.6.22 ...)<br>
<br>Thank you for your answer.<br><br>ps : pieter if you haven't tested freebob in 64 bits, perhaps you could give me some guidelines, to test it and make a report for you ?<br><br></div></div>cheers,<br><br>Mysth-R<br clear="all">
