Selon Jamie Bullock jamie@postlude.co.uk:
Do you have libaudiofile installed? I *think* Ceres3 uses this library for audio file access instead of the more common libsndfile.

I already had the libaudiofile on my computer, but after upgrading it ("apt-get upgrade libaudiofile") Ceres3 can finally load a sound file
Thanks a lot,
