My apologies, I did seriously try to figure out how to figure this out
and didn't come across anything that made any sense. So, I thought it
was a kernel bug...

Your suggestion to try aplay did indeed produce sound. It is the first
sound I was able to get out of this configuration ever. I attached the
output of alsa-info.sh with aplay playing, and with mplayer playing
and not working, and the diff. Thanks for your help, at least now I
have some clue about where to look.
