No Audio Ubuntu 17.04

Asked by Ashton Spina

Upgraded to Ubuntu 17.04 (fresh install). Found that there's no audio whatsoever. There's no audio controls on the right of the top bar. I've looked at alsamixer and noticed that some items, eg. headphones, is set to 0 and everytime I try and turn it up it just resets to 0. (Don't know if that's relevant?). Any ideas? Is there a way to reset alsamixer to default configuration?

I solved my issue using this. I don't know what was wrong but reinstalling pulseaudio brought back audio.
