BCD3000 : cannot set 4 playback channels with jackd

Hi,
I'm running a BCD3000 with Mixxx on an HP Mini with Xubuntu 16.04 and KXStudio repos.

I've got non problems to set-up the headphones channels (3-4) with the alsa driver, but when using jackd (with cadence) I can't start a session with 4 playback channels. My jack log :

Any idea ?
