[1.10.2] Overriding Minecraft Item Pickup sound?

Hey, so I wanted to play a different sound whenever a specific item is picked up, but all that plays is the original Minecraft sound. Please help.

My code:

	@SubscribeEvent(priority = EventPriority.HIGHEST)
	public void onItemPickup(ItemPickupEvent e) {
		if (e.pickedUp.getEntityItem().getItem().equals(DinocraftItems.CHLOROPHYTE_INGOT)) {
			e.player.playSound(SoundEvents.ENTITY_ENDERDRAGON_GROWL, 1.0F, 1.0F);
		}
	}

Thanks!
