ROG STRIX B350-F i'ts possible that a BIOS update mess the 5.1 audio?

[lewatoto]

The problem is the subwoofer don't sound when i choose the 5.1 mode if i configure as 2.1 subwoofer emits sound.

Already ask on microsoft support forum and the solutions they proposed to me don't work.

why i think this could be a bios problem? because the same issue occurs on windows and linux.

Info of my system:
BIOS version 5220
BIOS previous version 3303 - 3305 i don't remember exactly wich was.
Audio driver 6.0.1.8666
Windows 10 1909
Fedora 31
logitech z607
