NB to make this change permanent, I used HDA Analyzer tool, found the card 0, 
codec 0 and ticked the box which said input.

however, I undid this because it didn't work. I got my solution from: 

for ubuntu, all I had to add to:
    sudo nano /etc/modprobe.d/alsa-base.conf
    options snd-hda-intel model=dell-s14

and restart. I had changed the System->preferences->"multimedia systems 
selector" input to be alsa - but not sure I needed to.
