I am informed by the hda sound developer that alsactl is expected to be run
during the system initialization.  I was not aware of this requirement
previously.  This is a regression only in the sense that it worked before
(in linux 3.1) without alsactl.  However, now inclusion of an "alsactl
store" in the shutdown script and "alsactl restore" in the startup script
seems to solve the problem without the need for a dummy run of aplay.

I do think that this requirement should be made more prominently in the
documentation, preferably in linux/Documentation/sound.
