[Bug 398209] Re: Rosegarden does not play midi: Jack error

[raboof]

Running qjackctl is absolutely not a suitable solution to this problem.

The root of your problem is this:

cannot use real-time scheduling (FIFO at priority 10) [for thread
-1211020544, from thread -1211020544] (1: Operation not permitted)

JACK is configured to use 'Realtime' mode, but your system is not
configured to allow you to use Realtime mode.
http://trac.jackaudio.org/wiki/Troubleshooting explains how to
troubleshoot this problem - though I believe starting from Karmic this
is fixed in the default configuration (not sure).

** Summary changed:

- Rosegarden does not play midi: Jack error
+ Jack fails to start in real-time mode
