I always do a 'chmod 777 /dev/dsp'   and then a 'chmod 777 /dev/mixer' 
when I get that message.  Seems to get sound working.  You might want to 
do 664 or something less drastic if you're into security.  (I'm running 
K12LTSP at home for my family, behind a firewall, so it doesn't get hit 
that hard.)
