Both analog ports are marked as "not available", which means that to
PulseAudio looks like nothing is plugged in in either connector. This
is the reason why PulseAudio always picks the digital output on boot.
Broken jack detection is is a hardware or driver issue, which can be
worked around, see below.

It seems that I guessed wrong the card number. Card 0 seems to be the
HDMI card, while we're interested in the analog sound card, which is
alsa card 1. So change the script to this:
while read -r line; do amixer -c0 cget "$line"; done <<< $(amixer -c0 controls | grep Jack)
This information is required for me to give instructions for how to
work around the issue.
