Sound re-regression in 5.0

[Rhialto <rhialto%falu.nl@localhost>]

After upgrading to 5.0. my laptop got a bug again that was fixed before
(in 4.0 or 3.0, IIRC). The problem is that after a suspend/wakeup, the
sound is gone.

I had written a script to re-set the mixer to sane values (in
particular, various mute switches turned off). I hadn't needed it for a
while, but now I need it again.

(oh, and despite viaenv0, envstat doesn't see anything; that is
something separate of course)
