Ok, I've found a fix similar to Martin Sander's.
In order to get everything working, I installed: mpg321 ubuntu-restricted-extras PulseAudio PulseAudo-esound-compat libasounds2-plugins
I then ran: $ echo 'default_driver=esd' >> ~/.libao and restarted nautilus. I haven't checked if all those packages are necessary though.
