I wanted to try out oss because sound on alsa is not great. I am on Ubuntu 16.04.

Anyway I installed alsa-oss using 

sudo apt-get install alsa-oss

but it didn't recognize my sound card (it's Realtek ac290). So I uninstalled it and now I don't have any sound. I have tried reinstalling alsa using 

 sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2

but this doesn't fix anything, still no sound. When I type alsamixer in terminal I get:

cannot open mixer: No such file or directory

Please help!

sudo apt-get install --reinstall linux-image-extra-$(uname -r)

This command installed all the missing drivers and fixed the problem.

Source: ubuntu 16.04 reinstall all drivers
