No, I am not. But it seems Dmitry was right, at some point I bisected wrong by declaring some point good too early because I didn't have the bug on boot.
Perhaps I have two effects here: some bug resulting in sound distortion and some bug triggering that faster.
I will redo the bisection, but I fear it will take some time.
