>Description:
	  I get audio to work just fine after a reboot but once I
	  suspend and resume, I no longer get any
          sound: instead I get lots of these console messages:
          pcm0:play:0: play interrupt timeout, channel dead
 
 I wonder if this pr has anything in common with mine: different 
 hardware but similar symptoms.

 FWIW, this was on a ThinkPad A20: it's probably obvious that this was a 
 laptop, but in case anyone uses suspend/resume on a desktop system, how 
 the modules are handled might make a difference. Seems intuitive but 
 that didn't stop me wasting some time over it.
