Hello,
Minecraft seems to have an issue with THX support on Windows 10. Players with the Windows 10 version of the game that are running any Razer headset that is USB based and takes advantage of the THX audio engine are experiencing a very high pitched audio output that sounds like static constantly being played. This seems to be anything sound in game and has been a present problem in Minecraft for as long as I can remember.
