I have a problem on my Sony Vaio Fit 15 E (SVF1521C5E) running Ubuntu 12.04.02 x64. In particular I can't hear any sound from my speakers. I have no problem to listen with the headphones.

My hardware is the following:

$ lspci -nn|egrep 'ultimedia|udio|sound|AC97|ac97|EMU'
00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller    (rev 04)

$ aplay -l
