impossible to connect to jack


First time I launch Ardour, and it replies to me that it’s impossible to connect to Jack, for the possible reasons that 1) it isn’t launched, or 2) it runs on another computer, or 3) there’s another program named ardour. Then it asks me to quit and it ends.

What shall I do?

  1. Read the manual
  2. Install jack
  3. Make sure jack is up and running before starting Ardour
