There should be no reason an avatar can just have the ability to have 14,000+ audio sources with no problems at all. A lot of people abuse this manner to make avatars that completely overflow your game's audio, so you constantly hear a ringing sound. There is nothing to counteract this. Attempting to switch worlds, rejoin, etc. still continue the loud ringing sound. The only way to stop the sound is via forcefully restarting your game. I tried reporting someone who had this kind of abusive avatar to be met with "due to privacy considerations, we are unable to discuss the outcome of this review." Which I find preposterous.
