After that, and reboot, the Z515 is seen in /proc/asound/cards, and in 'aplay

This should not have changed the presence of cards in /proc/asound/cards,
only their order.
May-be it should not, but it actually did.
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
This indicates you have a configuration problem with your ALSA system: the
plugin infrastructure eventually references a non-existent sound card.
Did you really read my post?
the so-called "non-existent sound card" worked with vlc and audacity !!
with the 3rd one, you have the answer: just do
->sudo ln -s /dev/snd/pcmC1D0p /dev/snd/pcmC1D1p
This is completely wrong, this symbolic link should not be needed, and it
does not fix anything since it will disappear after the next reboot.
I have not read the rest of the thread, nor do I intend to, but I did not
want to let that kind of bad advice pass.
It will not disappear after the next reboot, thanks to /etc/rc.local.
OK, it's not a fix, but a workaround.
If you don't like it, you are welcome to propose a real fix.
Until that, the link is needed, and I don't think you are allowed to call
that a bad advice.
I would be curious to know how you interpret the mplayer error message
