This pin is powered off, because...

The headphone jack isn't detected.

SPDIF jack is detected.  This might confuse PA.

In anyway, the alsa-info.sh output you gave doesn't help for analyzing
the issue while the headphone is plugged.  It is off when unplugged.
It's the designed behavior.

So, please give the information during the headphone is plugged (but
still doesn't produce the sound from the headphone).
