Hello.

I just installed Ubuntu 16.10, the official release.
Very cool, very fast. But I fail to start Jack through qjackctl.


When I try (with Alsa), the error is:

and PID is always different.


Does anybody know what's wrong?

I solved it.

Jack works fine wth the library libjack-jackd2-dev but not with libjack-dev
