My USB headset no longer works. I installed kernel 5.3.0-43 from proposed and libasound2 from your ppa.

When I plug in a headset with a mic in the 3.5mm port, it still seems to use the internal mic instead of that of the headset.

I also get a lot of popping sounds in the 3.5mm headset when playing audio, but that might not be related to this issue as I had that on kernel 5.3.0-41 as well.
