Is this a desktop machine? Is the headphone jack that you're using in
the computer back panel? Alsa reports that "Front Headphone" is
unplugged, but "Speaker" is plugged in. The sound card on a desktop
machine might report the back panel jack as being meant for speakers,
while expecting that headphones are plugged in to another jack on the
front of the computer case (whether such jack actually exists depends
on the design of the computer case, and if it doesn't exist, the sound
card will just report headphones as unplugged).

I haven't seen alsa presenting a speaker jack before, which is why
PulseAudio ignores it. Try adding this to /usr/share/pulseaudio/alsa-

[Jack Speaker]
required-any = any

That should make a speakers entry appear in the Gnome sound settings.
