This has been an issue since early 2020. I have been having this Bug where when I launch (Minecraft Windows10 edition) and only this version of the game, it has a hard low tone static sound (but can get uncomfortably loud) with music, scrolling through the menus, and while in-game. I am using Razer synapse 3 with the Razer nari essential headset I'm running all sound through synapse 3. When I switch to my headset everything is fine. All my drivers are up to date. I do not have any issues with any other games it's just Minecraft windows 10 edition. 

I have tried this on other computers and all with the same problem.

steps to reproduce:

1. have a Razer THX headset
2. have Synapse set as default
3. have speakers set to (THX spatial - Synapse)
4. launch Minecraft windows 10
