[Ardour-Users] Fwd: No driver for Jack

[Greg Vaughan]

Ok I uninstalled jackd (and the rest of the apps tied with it) using
Synaptic then ran a 'which jackd' which returned no result and a jackd
--version which says jackd not currently installed... I reinstalled the
Studio Apps and ran into the same problem... how can I find and remove the
second version of jack? Any ideas?

Mark: Thanks... yes using Ubuntu Hardy and starting from graphical qjackctl.
Having said that Paul has it nailed.
Paul: Thank you very much. I added studio apps and already had the SVN jack
installed.
