I have recently been hearing a very faint static/buzzing sound on my headphones whenever I log onto minecraft, and it's more prominent at certain points in the game.

What I expected to happen was...:
I mostly just thought I could open up a new world and run it smoothly, without any audio issues since Ive been playing with this exact setup(headphones, pc, same minecraft launcher) for a long time now. 

What actually happened was...:
There was a very faint buzzing sound which was hard to notice at first. I'm not sure what's causing it at the moment. I mentioned about it being more prominent at certain points, which would be in the menu with all my worlds and also in-game especially when I hit "Esc" 

Also, this doesn't affect any of my other applications, the audio sounds fine on youtube its just whenever I head onto MC that this happens.

Steps to Reproduce:

Just to make it clear, Its not a guarantee that you will be able to notice it even if you follow all steps, since Minecraft was working fine for me a few days back. 
1. Plug in any kind of headphones(I had razer ones) or just use your usual audio device.
2. Sound enhancements were originally set to "ON" in the windows settings when this happened, but there was static regardless of that so it probably doesn't matter much.
3. Head onto vanilla 1.21, no mods, extra resource packs or anything of that sort. 

4. Go to the menu with all your worlds; the buzzing usually begins at this point 

5. Create a new world, log on and you should start hearing a very faint amount at this point. Hitting "Esc" seems to increase it more
