Red Hat Bugzilla – Bug 235624
Cannot get MIDI to play
Last modified: 2008-05-06 15:29:11 EDT
Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.Attempt to open and play MIDI files
3.No sound output, qjackctl cannot start as user, only as root. Opening a
terminal and typing qjackctl opens jack and allows jack to start. MIDI still not
available for user.
Browsing web yeilded permissions issue. Have not found solution as yet. Jack
appears to be in wrong location as when opening qjackctl as su an error message
appears: Warning: no locale found: /usr/share/locale/qjackctl_en_US.UTF-8.qm
but jack opens and can be started from terminal session as su.
I'll push today the new version of the jack-audio-connection-kit to the devel
repo. After it is built try to rebuild it on your fc6 box and after update
just add yourself to the jackuser group.
The jackuser group is discussed at bug #221785. Please, refer to that bug
I have tried to update, but the repository doesn't respond. I added myself to
the jack group. Attempting to open Jack gives this message:

Really, the last jack is allowed in the new rawhide repo (F-8 aka devel). But
that repo isn't published while now (if I understand correctly). I'll put new
jack in the F-7 repo in the near future (may be one or two weeks).
Fixed for FC6, F-7, Rawhide. Please, check it and reopen this report if needs.
I believe I have the latest version of Jack as I have re-installed my operating
system as Fedora 7. Attempts to open jack gives the following:

All this stuff seems to work ok, even with Rosegarden on FC7.

Since my last attempt, I have installed Fedora 8 with the hopes the interfaces
Reinstalling jack, qsynth, and rosegarden using your tutorial did not solve my
problem. Jack would not start at all. One of the messages in the Jack messgae
cannot use real-time scheduling (FIFO at priority 10) [for thread -1208645952,
from thread -1208645952] (1: Operation not permitted)
Un-checking the realtime parameter allowed starting.
Qsynth and Rosegarden then recognized jack as running, but I have no audio
output. Changing any other jack settings stops jack from loading.
Am I getting any closer to a resolution, or should I forget playing midi through
rosegarden? My wife would really like to use the program for music editing, but
is currently using a windows application because of the difficulty getting
interfaces to work in linux.
