An Entity can have a single physical representation. Sound can be turned on and off with active (which is distinct to entity visible flag). Sound derives from Entity so if you have a Sound you can do any of these functions as well as the functions in Entity. You can do entity:IsA(Sound) to see if a particular entity variable is a Sound type entity.
||Set whether the sound is playing or not.|
||Set the SoundAsset that this entity plays|
||Set the volume of the sound (0 = Silent, 1 = Full volume)|
||Set the pitch of the sound (1 = Default pitch, 0.125 = 8 times slower, 2 = 2 times faster)|
