If you delete a sound entity, the active sample does not stop playing and continues to loop. If you move outside of the max radius boundary the sound then stops playing.

Reproduce:
Add a sound entity
Delete the sound entity whilst inside the max radius boundary
The sound will continue to loop indefinitely despite no entity being within the world.
