Public bug reported:
Several days ago I found huge lags over all system on my Ubuntu 20.04.1
LTS. Today I think found the problem, but not the reason. So when I open
Settings -> Sound menu, the CPU usage comes to about 100%. If I close
Settings window or go to other tab, it becomes OK. Nothing special in my
sound configuration - monitor and notebook with built in audio and
Bluetooth headset. Same worked just fine on Ubuntu 18.04 LTS.
