No audio on Intel Z77 "Panther Point" HDA (8086:1E20)

Hi,

I'm having some difficulty with audio with Intel Z77 "Panther Point" HDA (8086:1E20)
I can see HDMI out for the integrated HDMI but not the analog audio for my headphones.
I can't see any mention of the output in pavucontrol or the mixer.

Output of cat /proc/asound/{cards,devices,modules,version}:

I'd be grateful for any pointers offered. My googling has come up empty.
