I have something similar. By default I get sound through the
headphones and not though the speakers. If I create
/etc/modprobe.d/local.conf, with contents

options snd-hda-intel model=imac27

I get the opposite - sound on the speakers but not on the headphones.
In both cases, nothing I do with alsamixer -c 0 makes any difference
to the other output.

This is on a new imac, with an up to date F17.
