[LAU] Jack fails in QJackCtl but not in command line

Hi everyone! To launch jack I run: /usr/bin/jackd -P80 -dalsa -r44100 -p256 -n2 -Xseq -D -Chw:5,1 -Phw:5,0 This is what I have in my .jackdrc. In command line, there is no problem. It works perfectly. But if I try to launch Jack with this parameters through QJackCtl, I get this in the message window: creating alsa driver ... hw:5,1|hw:5,1|256|3|44100|0|0|nomon|swmeter|-|32bit The 5.0 output becomes 5.1. I don't understand why. Does anyone have an idea of what happen ?
