I'm having trouble with my sound after a couple of tries. My sound card is not showing and not having any output. I wasn't able to fix the sound of my ubuntu. I mistakenly do dist-upgrade and don't know how to revert to the working version in Ubuntu 16.04. It was working before I've done dist-upgrade.
I tried all the reinstall and update from all google search I can find. In no avail. This is my last resort to ask for help.
