If you’re playing multiplayer and this is happening, I recommend making sure ‘they’ don’t have the “/taunts” option disabled under the Games tab of Options menu, or the “Disable Taunts” option enabled on the Audio tab of Options menu. For whatever reason, the game mutes your ability to hear their taunts if they have “/taunts” disabled on their game. In your case, maybe it’s also affecting yours that you do, too? Either way, it’s worth double-checking both these settings on your machine and theirs…
