Some news:

I reinstalled jackd1 instead of jackd2. QJackCtl now runs jack without error. But ladiconf depends on jackd2. So I can't use Gladish, which is very annoying for me.

Furthermore, Puleaudio sink and source are no more created automatically in Jack. I have to add supplementary lines in /etc/pulse/default.pa, then kill Pulseaudio, and when it restarts, it appears in jackd connections. It's also not very practical.

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
