Sound (Ambient)
Customize the sound the machine makes when running/idling/erroring.
You can define a sound that will play when the machine is in a specific status (corresponding of where you put the property in the appearance json).
The sound must be a OGG file and must be loaded in-game. Sounds are different than models and textures and must be registered to be usable so for using custom sounds you will have either to use a mod that let you add sounds to the game or replace an existing sound with a resource pack and use it's name in the property.
The property must be defined as such :
If no sound property is set the machine will just make no sound.
