Hi Bernard,
lilypond is the program that does the actual typesetting. You can check
if it is installed by typing
dpkg -l lilypond
in the console. If it is not there, install it with
sudo apt-get install lilypond
I guess that the problem that the typeset does not work is caused by not
having lilypond installed.
Regarding the sound output: To know which configuration is working,
please look whether you have a sound server running (I guess that you
have) and which one that is. If you don't know what a sound server is,
just tell me which desktop environment you use (KDE, Gnome, LXDE, ...).

1) I don't have Lilypond installed unless it got onto my machine as part
of another installation. It does not appear on the Ubuntu Software
Centre where I get my applications from. The 5 things listed when I
search on Lilypond are Frescobaldi, NTed, Rosegarden, Denemo, and
Scolily Score Recorder.
2) There are no error messages, just no playback sounds (incl no sounds
as notes are input) and blank print preview panes.
3) Sorry, I don't understand what you mean by "What happens if you
export to lilypond and compile manually?" I really am not even a
beginner programmer - I wouldn't know where to start.
4) I'm really not sure if I have the sound set up correctly. I can play
music that is stored on my computer with rhythmbox, and BBC iplayer and
other web audio works fine through soundblaster. I have tried a lot of
combinations of settings in Denemo preferences "Audio backend" and
"output device", to no avail.
5) When I'm trying to get Denemo to produce sound I turn the PC on and
go straight into denemo without switching any other program on, so I
don't think the device is busy with another program.
Hope that helps.
Let me know if you think this is a lost cause!
Bernard
