Hey there @tigerblood,

Thanks for sending this along. We loaded up the game client and only notice once instance of the game in the sound mixer, so what you're experiencing is definitely not by design. We'd be happy to help you out!

Does this occur each time you play the game, or has this only occurred once? Please give a quick try to restarting your computer, which will close all of the open processes. From there, launch the game and let us know if a bunch of instances are showing up in the volume mixer.
