PSA: This may be related to a broken headphone jack that is supposed to
detect whether headphones are plugged in and change output accordingly.
Work around in ubuntu right now is to run alsamixer from terminal,
select correct soundcard, then disable auto-mute, then unmute and turn
up speakers.

Public bug reported:
Under sound settings only headphone output is listed as an option, no
internal speakers are listed. Headphone playback does work. In
alsamixer, speaker output was at 0 and muted, but unmuting and
increasing volume does not produce playback in speakers.
