Well, I restarted again, and then alsamixer and aplay worked, though with no
sound.  I hit the VolumeUp button, and then it worked.  Okay.  So the Mute
button seems now to mute at the hardware level, and not unmute when pressed
again.  VolumeDown does nothing.  VolumeUp simply unmutes.  The Mute button
didn't cause the ALSA problems this time as before.
