Yeah, I've got a MacBook 5,2 too, and I can't make ALSA drive the headphone jack at all. The hdajackretask rerouting to the line-in (then plug the headphones in there) workaround that Tobias suggested is indeed very hacky, but does work.

Alsamixer does recognise if I plug in the headphones and does automute the speaker-sound but there is no sound on the headphones. The speakers work well. I installed some extern drivers by Realtek but this crashed the whole sound and I did a fresh installation of Ubuntu 14.04. The only thing I changed now is alsa- base.conf, I added the recommended line "options snd-hda-intel model=mb5" for my Macbook.
