After upgrade to 20.04, cursor scroll stutters when earphone is plugged in

[Agniva De Sarker]

Hi,

I am having this weird issue after upgrading to 20.04. There are primarily 2 issues, all related to the fact of inserting earphones in my laptop. The moment I insert the earphones:
- The cursor movement starts to stutter and eventually stops after a second or two. This happens when I am trying to go up or down in my code editor.
- Paused Youtube videos automatically start resuming themselves. It seems like this is a feature somewhere, but after a lot of googling, I was unable to find anything related.

The issues only happen when I plug in my earphones and stop when I take them out. And this started to happen immediately after I upgraded to 20.04.

Any guidance will be much appreciated. Happy to provide more info.

Thanks.
