As the title says, my sound has gone missing after an update with update-manager. I have found the solution before, but then had to reinstall Ubuntu. It can't even detect my audio card. Here is a screenshot of the sound settings. Sound Settings screenshot

I have tried every single thing, including killall pulseaudio, updating the sound drivers, and removing the alsa plugins. This all happened after I updated through update-manager and I was wondering if I could rollback to stock without losing any data.

Note: This is not a duplicate, I have tried (I'm pretty sure) every single possible solution.

I've got exactly the same issue with the same version of Ubuntu. It's a shame :/ –  topr Feb 22 at 14:34
