No soundcards detected Ubuntu 14.04 Dell Inspiron [SOLVED]

Hi,

I was having problems playing sound through HDMI with my dell inspiron laptop and after removing (and reinstalling) two packages the sound settings only lists 'dummy output'

I've been following the steps from https://help.ubuntu.com/community/SoundTroubleshootingProcedure and it advises to post a question with the output from this command

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

The output given is:
