Description paul beard 2002-10-30 20:00:12 UTC 
	  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.

How-To-Repeat:           see above: it reliably occurs each time

Submitter notes that his workaround is to load and unload modules 
rather than compiling them into the kernel.
Comment 5 paul beard 2004-09-09 22:30:29 UTC 
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.
