Public bug reported:

My Lenovo ideapad 330 laptop with Ubuntu 18.04 sounds works fine
initially.  However,  when I close it down (to sleep) and then return,
all the sound disappears.  The only way to get back the sound is to
restart the laptop.  The issue seem to start after a recent automatic
update.
