Not sure what more you want me to report. I've followed the guide on http://voices.canonical.com/david.henningsson/2014/03/07/headset-jacks-on-newer-laptops/ and I tried setting both options snd-hda-intel model=dell-headset-multi and options snd-hda-intel model=dell-headset-dock.
You are correct that there is only a headset jack on this laptop.
