Will try that when I get to that desktop.

Alsa-info output is available as
https://bugzilla.kernel.org/attachment.cgi?id=107242 . Note that
headphones produce sound by default when plugged into that rear green

OTOH, your comment does not address the "Or to say that this HDMI
output, ultimately, leads to headphones" part of my e-mail, or users
with non-HDA sound cards that may still need (for the purpose of
filter application) to say "this leads to headphones". AFAIK this is
not doable with hda-jack-retask.
