Right I fixed this.

Looking at some of the files that didn't play, they all seemed to have AAC 
audio.

I searched around a bit, and there was a few posts (from 2008-2010) with the 
same sort of issues.
It was fairly out-dated discussion, but somehow they had exactly the same 
symptoms.

Anyway, installing the Ubuntu package ubuntu-restricted-extras fixed it.

That's:

     # sudo apt-get install ubuntu-restricted-extras

For the noobs.

I also did an dist-upgrade, although I'm fairly sure I did this just after 
installation a few days ago.

Anyway, with the restricted-extras and dist-upgrade, it's all working well.

But I still don't know what was wrong.
