In Minecraft Bedrock Edition 1.21.73, on Windows 10 (build 19045.5737), enabling the spatial sound effect in system sound settings and setting it to "Windows Sonic for Headphones" causes all in - game sounds to have a strong electrical current noise. This might be due to hardware or software settings, but no such issue occurs in other sound - producing applications or web pages. The headphones and speakers function normally elsewhere without the electrical current noise. I've included two images for reference below. One is the original, and the other is a machine - translated version.
What headphones and speakers are you using?
