Headphone output still doesn't work. Plugging the speakers into the
front headphone jack, I went to Applications/Sound and Video/PulseAudio
Volume Control, then set 'port' to 'Analog Headphones'. It is not muted
and shows sound when playing an ogg file, but no sound comes through the
speakers.
Plugging the speakers into the back of the computer and selecting
'Analog Output' in PulseAudio Volume Control produces sound (everything
else looks the same as when selecting 'Analog Headphones').
