All Minecraft Sound stops playing if you unplug and replug your Headphones/Headset and this is fixed only if you restart the game, or reload the sounds by reloading the resource packs, which both take a CRAP lot of time when you are playing with about 1000000000000 mods installed, but this isnt a Forge bug or something, it still happens when I'm playing Vanilla!

P.S. Just in case i tested the G230 headset, the KRAKEN Pro, Some Wireless Genius Headphones and my Laptops Built-In Speakers.
