Computer: Dell XPS 13 9350

Ive converted to Ubuntu on my laptop. Im new to the whole experience so bear with me.

Ive had some issues with audio. I started on 14.04 and the audio worked there and when i tried to upgrade to 18.04 the soundcard disappeared. I had to go via 16.04 and the sound was still working there.
Ive tried different approaches posted around the web but nothing has worked

Can anyone help me?

I dont know if its relevant but ive uploaded the output from Alsascript and im attatching the link here
