The linuxulator does not handle the sound stuff in a special way. So  
it is either a problem because of a recent change to the soundsystem  
(I don't remember one, and we would need the output of "dmesg | grep  
pcm" and "cat /dev/sndstat" as a start), or because of a recent change  
in some linuxulator code not related to sound. There where several  
changes in the linuxulator since Feb, so if you could do a binary  
search to nail down the change we could take a look at that change.

Bye,
Alexander.
