It's unlikely that any of the controls in pulse itself will help as it 
only exposes a very minimal subset of lower level alsa controls.

Chances are the problem is at the alsa level, more than likely a control 
toggle or an independent headphone volume slider that is set to zero or 

To access alsa configuration, you will need to run the alsa mixer on the 
hardware directly rather than on the "default" alsa device which is 
probably setup to direct things to pulse (and thus will only expose 
afore mentioned minimal controls).

To do this in a console you can run: alsamixer -c 0

Or you can use a GUI alsa mixer like gnome-alsamixer which will only 
look at hardware devices.

HTHs and you find a solution fiddling about with a control there.
