Re: [LAU] : jack CPU % is going crazy !

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

I am a bit lost !! :O[
