This pin is powered off, because...

                iface CARD
                name 'Headphone Jack'
                value false

The headphone jack isn't detected.
Meanwhile,

        control.22 {
                iface CARD
                name 'SPDIF Jack'
                value true

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).

According to the reporter:

"Actually, that information was when the headphones were plugged in,
but the detection is incorrect.  (Linux thinks the headphones are
unplugged, when they are actually plugged in."

Thanks,
Laura
