No sound - Ubuntu 20.04 LTS
Installed Ubuntu 20.04 and I do not have sound.
I already tried many ways to solve it but the problem persists. When i run alsa mixer this comes out.
sudo apt-get remove timidity
sudo shutdown now -r
That's all, problem solved.
I had this same issue a few days back when I updated my system to kubuntu 20.04. All I needed to do was type alsactl restore into my console and my audio jack started functioning again.
Edit: I'd advise you to use a .desktop file or keep it handy another way, because you'll have to run this script whenever you plug in a pair of headphones.
