I've got some issues with my microphone recently.
It started sounding like talking through a fan even though the microphone itself appears to be not broken.
So it seems like a software/driver-related issue.
(As you can hear, the playback from the microphone itself just works fine. But as soon as it gets used in any other application it starts sounds like dung, VoiceMeeter was just an example, same in Audacity, Games, ...)
