First, let me compliment your in depth description of your issue. Second, I am going to throw another hat into this particular ring. However, I am on PC using Corsair Void V2 headset. I have experienced this issue with several games including Icarus, Gray Zone Warfare and Cities Skylines 2.
I have tried uninstalling Battlefield 6 and completely redownloading the game, changing audio profiles in Windows and I have double checked all drivers and software related to Corsair's iCUE program. I have disabled Windows audio enhancements and hardware acceleration for audio, and completely removed and reinstalled the RealTeK Audio drivers.
While I do not believe Battlefield 6 is the root cause of this issue it is game most frequently effected.
