This is a feature I thought we would have had from the start. Most audio inputs for animations on avatars are usually music or some form of 2 channel sound. This is a big issue when it comes to phase cancellation. If sound sources on avatars could be set to 2D but have a cutoff volume based on range everything in game would sound so much better, and it would also allow for more creative placement of sounds in game such as boom boxes on avatars and proper reverb in the sound files them selves to be played by the sound source. (This usually sounds much better than reverb zones granted it can be from a convolution reverb that takes an impulse to drive the reverb itself.) I really hope this feature gets taken into consideration as sound is possibly the most important thing for immersion aside from the visuals.
