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 ?

    
    Sound card: Fast Track Pro

    OS: Ubuntu 12.04

    Jack: jackdmp 1.9.8

    QjackCtl: 0.3.8

    pulseaudio-module-jack installed and Fast Track Pro disabled in
    PulseAudio
