Public bug reported:

Sound stops working on a laptop running Ubuntu. When the laptop is left
alone overnight, the sound works the next day. I'm not quite sure why
this would happen. Dummy Ouput is the only device shown once the sound
stops working.

"aplay -l" command shows the following:
aplay: device_list:268: no soundcards found...
