Minecraft's sounds are highly distorted, for any sound including different modpacks with different sound, this has been a really annoying bug that has bothered me for a while. It really gives minecraft a disadvantage at playing the game. (ex. I died of a creeper behind me) I've researched online about this problem it seems to only have effect for razor headphone users, I've tried every possible way of fixing the bug, nothing works, It also seems this bug has been around for some time. So maybe you guys can work on it now. Here's a video to show what's happening. https://www.dropbox.com/s/wpxlbo24ja04s96/minecraft%20sound%20bug.mp4?dl=0
