Actually I'm on 0.9.13-6! Tesekkur ederim. :) Do you mean I should go
back to an earlier version?

I realised I wasn't a member of the various pulse groups so I fixed
that. It didn't really improve anything. Then I tried changing the
tsched parameter to 1, so I now have:

load-module module-hal-detect tsched=1

It's much much better but still far from perfect. Amarok hasn't
crashed yet (fingers crossed) and CPU usage is much better. I'm still
getting lots of skips in the audio when playing back an mp3 in amarok
though.

The last few log messages are below:

Thanks, Chris.
