Andy,
This is looking more and more worrying !!!
This has been an ongoing problem for me for quite a while. I cant
remember 'exactly' what other solutions I have tried, but it did involve
attempting to recompile Alsa modules.

Hey.
Really appreciate this bit of help !

Oh dear. Can you look in /var/log/messages for unknown symbol info, eg
tail -n50 /var/log/messages
Did you unsuccessfully recompile the Alsa modules using the
alsa-project.org stuff?
What does
modinfo snd
say?
