Public bug reported:

When I play back audio, I get only sound from headphones, not from the built-in 
speakers. I'm sure that speakers aren't muted; see the attached screenshot of 
my desktop's audio output control panel (its meter shows activity, so audio 
playback seems to pass).
Also, I have been able to get sound with LUbuntu 14.04 (I'm on XUbuntu but I 
had the same problem with the Ubuntu Live DVD).

Thanks for looking into this
