There is GC allocated every time we play audio via a StudioEventEmitter which comes from RuntimeManager.FindOrAddAttachedInstance. For something that is called so frequently, I would think making this not allocate would be ideal (e.g. by having a pre-allocated List instead).
We’re kind of able to work around it by inheriting from StudioEventEmitter with our own class and avoiding using the internal logic, but that seems like a bit of a shame.
