   This relatively simple system ought to be the basis for excellent
   cooperation between PulseAudio and JACK. Unfortunately, it relies on
   everything being correctly configured for it to work, and Ubuntu
   have repeatedly failed to get this configuration correct.

 <h2>Problems with JACK configuration<h2>
 
-<p>
-  To function as intended, JACK needs to run with access to two
-  operating system facilities called "realtime scheduling" and "memory
-  locking". This means that you, the user who starts JACK, must be
-  allowed access to these facilities. By default, Ubuntu does create a
-  user group that has this permission but ... it does not put new
-  users into this group by default. Consequently, you will not have
-  permission to run JACK in the way you should.

-
-<h5>Symptoms</h5>
-
-<p>
-  A message like "Cannot lock down memory" in the output from JACK as
-  it starts up. This output may be "hidden" in the Messages window of
-  QJackctrl (aka JACK Control), so you should check there.
