If its all working now I can start uploading the scripts for user which will 
make it easier. I mean for users and for user-scripter. Menu options and easy 
scripts.

Thank you all for the hard work, this is really a great thing.  Finally I will 
be able to send Denemo itself to my friends and tell them to install it (in 
Windows) and they are not going to say "I can't hear anything, this is a crap 
software".

Should the choice be really on compile time? Maybe I just got you wrong but I 
think of Binary Packages in distributions and it should be better to always 
configure Denemo with --enable-fluidsynth and --enable-jack.

First check should be on configure. Compile only with sound if the libs for 
jack and fluid are there (It should be possible to have Denemo completly 
without sound, just as lilypond-typewriter). 

And second if both soundlibs are compiled in it should be possible to switch in 
Denemo. 

There are more things, for Jeremiah:
1)The Button "Restart Fluidsynth" is currently buggy. You have to switch from 
JACK to ALSA manually, but then press "ok", leave the pref-dialog, go in there 
a second time and then press "Restart Fluidsynth" to make it work. Isn't it 
better if "Restart" directly reads the value of the driver-drop down box.

2)Is is possible to auto-detect the audio driver every time Denemo starts? For 
example if JACK is not running use ALSA instead. Or maybe introduce "Auto" as 
drop-down option so that the user has a detailed control if he wants to force a 
driver or let the app decide.
