I am stuck with my audio jacks not working on a B450M motherboard and Ubuntu 20.04. I have installed the last kernel but jacks are still not detected.
If anyone wants to have a look, complete logs and infos there: https://askubuntu.com/questions/1238592/front-and-back-audio-jack-of-b450m-ds3h-cf-not-detected-no-sound
