Have you tried to list and use available cards from alsa perspective
(your device names may be different)?
I'm not sure that this is the problem, as the sound works correctly
with the headphone, even with speaker-test !
I already tried with the different devices given by "aplay -L",
and of course checked the output levels with alsamixer.
for example: "speaker-test -Dsysdefault:Generic -c 2 -t sine"
but never got any sound through the speaker.
I remind you that the hardware is not involved, as the sound works
with Windows 10.
