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 ...

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
