The problem solved itself so in my case it isn't to do with the latest kernel. 
I followed the steps listed at 
http://forums.fedoraforum.org/showthread.php?t=206868 even though I didn't 
think it was really going to help and initially, it didn't.  

But after two reboots, sound decided to work again. It didn't on the first, 
worked on the second. 

<Shrug> If we had 26 hours in the day, I'd spend some time trying to figure 
out exactly what it was that fixed the problem.... :-)
