In order to compile with sound playback on vanilla ubuntu 9.10 and 10.04 (which have pulseaudio and not jack), I had to install libpulse-dev
sudo apt-get libpulse-dev
Then, after compilation, the option to use PulseAudio appears in the preferences (General --> Playback audio device)
Could you add this in the INSTALL.ubuntu file ?
(NB: I had compiled SV before installing libpulse-dev and I had to do a "make clean" plus a "qmake-qt4 -nocache" in order to compile with pulseaudio support)
(NB2: to get portaudio support, the lib to install seems to be portaudio19-dev)
