When plugged in, the headphones played and the speaker muted.
Unplugging the phones, the speakers play.

At the risk of being redundant, here's what I have so far:

First off, with plain kernel v3.2.0-1-686-pae, I run 'audacious' with a
playlist.  'pavucontrol' shows movement.  The speakers are mute.
Plugged in, the headphone are also mute.

Then I ran 'amixer -c0 set "Auto-Mute Mode" Disabled'.
The speakers (line out) play.  Plug in the headphones, the speaker
mutes, the headphones play.  Unplug the phones, the speakers play.


HTH...
