I think that would be ok. Those who use jack have to set things up, and
so setting the Denemo prefs to use jack would be expected by them.

This I don't understand. I start with a simple Debian Stable
installation. If I set pulseaudio in the prefs I hear nothing - the
output is

fluidsynth: error: Couldn't find the requested audio driver: pulseaudio

 I hear things if I set oss. So it seems that a naive user installing
the denemo package and just starting denemo will hear no output unless
he has installed pulseaudio (whatever that is). Perhaps when I set oss I
am getting a side effect of some package that I have installed for some
other reason?
Also, just reading your patch, it seems that the lines

 #ifdef _HAVE_JACK_
   ret->midi_audio_output = Jack;
 #endif

have been left in and (as you have compiled with --enable-jack) I would
have thought it would default to Jack midi output.

It is quite alright to ignore all my comments if I am just barking up
the wrong tree. I am really quite lost in this deluge of drivers and
outputs and so on. If you are happy that someone installing and running
denemo will get something working straight away then I am sure that is
fine.
