After about 30 seconds of the client being connected to this game, their developer console log is flooded with this until they leave the game, and causes the sound service scripts to eat up more and more memory.
You can put a modified version of the sound script in StarterPlayer or just put a script in there named Sound with absolutely nothing to disable it completely, your call.
I have a fork of the Sound script placed in StarterCharacterScripts. In the server script, there is a line of code that creates a RemoteEvent called CharacterSoundEvent in every sound added to the character. Just below the event’s creation but before the parenting, I connect a blank function to OnServerEvent as shown above.
