Adding some extra notes about this: All the files are set up correctly to play candle ambient sounds: The files are in sounds/block/candle, sound_definitions.json has the sound event, and sounds.json hooks it to "ambient.candle". The issue is that Minecraft is not calling the ambient.candle event from sounds.json in-game.
