Sound Issues – How to Fix Sound Not Working on Ubuntu

Using an ASUS TUF FX505GD. My Speakers just stopped working and I think is something to do with my graphics card.

This is what it shows up when I run lspci:

And this is what it shows when I run aplay --list-devices:

**** List of PLAYBACK Hardware Devices ****

Would really appreciate some help.
