I have modified my setting as you suggested.
speaker-test is now producing sound with both 5.12.13, and 5.15.5. Which is
actualy 5.15.6, not 5.15.5, by now. It got upgraded a few days ago. I don't
know what is the exact change that made it working. I have done several
other chnages in the last couple of days.

With 5.12.13 I invoked speaker-test either by
speaker-test -c2 -Ddefault:PCH
or by
speaker-test -c2 -t sine -f 1000 -Ddefault:PCH
With 5.15.5 I invoked speaker-test by similar commands. But, usualy, ommiting
-Ddefault:PCH.

I don't follow you. What is only about speaker-test and aplay?
Is it that my report is only about speaker-test and aplay?
I haven't tried anything else, other then speaker-test and aplay. In fact,
I used aplay only with -L or -l options for its reports. I didn't try to
play any sound file after I realized that speaker-test is failing with 5.15.5.
