Ubuntu – How to fix 3.5 mm audio jack not working after upgrading to 20.04

20.04audio-jacksound

I tried Ubuntu Vanila, Mate and Kylin (all same version 20.04) still the same. It plays fine with the inbuilt speakers but when a headphone is plugged in there is no audio. In the speaker settings it changes from speaker to headphones but doesn't play. Then reinstalled 19.10 and now audio is fine.
