This should have read "reading various Linux Audio mailing lists". Sorry!

Bizarre. I had a quick look, and didn't see the same problem. At the 
moment, I have both rtirq and rtload enabled, according to both the 
graphical 'Service Configuration' window, and ntsysv (which I have just 
learnt about - thanks!)

I'll disable rtrload, and see what happens.
