I can't see how this commit fixes your sound problem.  Are you
loading/unloading the device drivers (i.e. via /etc/rc.suspend,resume)?
I could see that helping.  Or is the problem fixed even without doing

It's often difficult to sit down and come up with the optimal test plan
(for instance, binary search) and then stick to it.  Usually after a
while, the temptation is too great to just try what you think will fix it
and then get lost in random, duplicative tests.  I think this is related
to the high we get from succeeding in record time due to intuition.  Of
course, we don't later remember the hours spent pursuing unfruitful
intuitions and compare, we only remember the good ones.  :-)
