I got the microphone to work by adding the following line to

/etc/modprobe.d/alsa-base.conf

options snd-hda-intel model=dell-bios

This changed the sound preferences to have three options Microphone 1,

Microphone 2 or Microphone 3.

Microphone 1 worked with skype and you can see the meter change when

noise / voices are detected.

It would be nice if this worked without this mod ;) but at least there

is now some info on how to get it working.
