Ooops I have misleaded you with PinConfigOverride that's for all the Macs,
dont look for it anymore.
Node 0x17 [Pin Complex] wcaps 0x40058d: Stereo Amp-Out

Looking at your alsa-info, this is your Bass Speaker Playback Switch.
It is in current Power setting=D3 and actual=D3.
It should become D0 to be turned on.
Not sure if you can do this via alsamixer -c0 ?(or whatever number is your
card).
there is also a way with hda-verb (make sure you have hda-verb installed
(from <ftp://ftp.alsa-project.org/pub/tools/alsa-tools-1.1.7.tar.bz2>
alsa-tools <ftp://ftp.alsa-project.org/pub/tools/alsa-tools-1.1.7.tar.bz2>
?))
According to https://www.kernel.org/doc/html/v4.16/sound/hd-audio/notes.html
power_save_node (bool) advanced power management for each widget,
controlling the power sate (D0/D3) of each widget node depending on the
actual pin and stream states
could be a permanent more elegant solution in a hda-jack-retask.fw patch,
but no idea how it should look for that widget exactly, Takashi can suggest.
You can try for now enabling that Power: setting=D0, actual=D0
if that will help you probably:
Documentation is at:
https://www.intel.com/content/dam/www/public/us/en/documents/product-specifications/high-definition-audio-specification.pdf
Page 153 is of your interest.
0x705 is the SET verb, 0x00 should be fully on D0 state
# sudo hda-verb /dev/snd/hwC0D0 0x17 0x705 0x00
you can get the value from the codec back:
# sudo hda-verb /dev/snd/hwC0D0 0x17 0xf05 0x00
Hope that helps, if that solves the solution as a dirty thing you can put
that hda-verb command in your /etc/rc.local (depending on the distro
rc.local maybe deadend).
