Comment 73 for bug 400682

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').
