There is a solution to the high-frequency squeaking of the speaker!

[Linkinterteid]

The problem has already been solved by other people, I tried the build with this fix and it really works, no more high-frequency squeaking! Why can't this be implemented into the main system??? What's stopping you? Are there any conflicts with performance???

This has been fixed by me in #1179 and will be included in 4.3.
