This turned out not to be correct - I was testing with HD video and they do
work - but SD will fail.

I posted to the mplayer list and one of the devs thought it sounded like a
reclocking issue and suggested I try playing audio while running glxgears.

With vblank_mode=0 it does help but not totally cure, the audio progresses
normally as opposed to being mostly stuck, but is still distorted.

Running a nexuiz timedemo, however totally cures it!

So it seems that loading up my system is the way to fix and why my HD vids
worked but failed with UVD.

I have tried disabling cpufreq on_demand and also forcing dpm auto/low/high,
but there is no difference - I need load to make it work.
