I might have a solution for the upper left volume bar.
I found the solution in the windows audio settings.
My system is a windows 10pro x64
if you go to device settings and open your audio properties, you will find to the left side on
the page additional device properties.
open and you get the old version
go to enhancement box
there you see a checkbox immediate mode mine was checked unchecked it and so far tested it but it’s gone .for now
hope more people are helped with this topic.
