Well I think at last I have solved this problem!  Not mplayer's fault,
either :-)

I disabled volnorm for a couple of weeks and everything played fine,
but then I noticed Audacious was also clipping with the volume
normalisation plugin, which I never remember it doing either.

I upgraded my kernel to 2.6.28.3, and tried ALSA 1.0.19 (having
previously had major issues with 1.0.18.)  So far it seems fine, I
re-enabled volnorm in mplayer and I haven't had any clicks or pops
yet, and Audacious no longer clicks either in the places that it used
to 100% of the time.

So it looks like this is an ALSA issue, rather than an mplayer issue.

Cheers,
Adam.
