Jack & Ardour updates

Thu May 9 20:19:35 UTC 2013

Hey Leo,

your version of jack is confusing to me. If I look at packages.ubuntu.com, I
can't find that version... whatever. Try "sudo apt-get install jack2". Than jack
should be version 1.9.9.5. I'm using ubuntu studio 12.04 with some kxstudio
repos (main ppa, kernel, plugins, latest, kxstudio).
Do you have a realtime kernel? Mine is 3.2.0-41-lowlatency-pae on my notebook.
So please make sure that you are using jack in realtime mode.
Another possibility I can imagine is that you are routing output to pulse
instead of system?

Regards
Tim
