Unfortunately that doesn't help.  Once the machine is in this state,
then even after using "lsof" to track down all processes that are
using the sound device, and killing all of them, the *next* thing to
access the sound will play for a few seconds and then lock up.

I once got it to clear up by unloading and reloading all the
sound-related kernel modules, but that doesn't repeatably work either.
