Hmmm... I can understand now... Well.. I tried now the version of Jack on kxstudio testing ppa<https://launchpad.net/~kxstudio-team/+archive/testing>and the problem is the same... :(
This ppa was install jack2, jackd and jackdfirewire packages on version 1.9.9 but the package libjack-jack2.0 is mantained on version 1.9.8 The next step will be to compile jack packages on version 1.9.9 Ivica, or anyone, you have some information how can I compile that? For that I need some help.
