actually it seems the problem is with the midi sequencer
while trying to start qjackctl

or if I start jack from the command line and then try to start qsynth
Qsynth1: Failed to create the MIDI driver (alsa_seq).
No MIDI input will be available.
modprobe snd-seq-midi
may have solved the problem testing some applications to verify
ok musescore is working now
----------------------------------------------------------------------------------------------------------------
I have been running musescore on fc16 and noticed on a test install of fc17
that musescore would not play any midi file. I thought it might be a fluke
of the hardware (laptop) . But this morning I booted my prod system
with fc17 and still a problem with musescore the play button is frozen.
Not sure if I should open a bug report?
The musescore preferences are set to
use internal synthesizer
portaudio
the buttons for portaudio api and device do not respond to mouse clicks
When I start musescore from the command line I get the following messages
mscore
