It seems to be a cart before the horse issue: items are registered before sounds so the record has no sound attached to it. I can get around this by using a static initialiser, but I'm looking for other options. I also have a similar issue using custom spawn eggs: the entity type is a null. In this case I'm using spawn eggs directly so they can be placed in my mod's creative tab.

 

@ObjectHolder(References.MODID)
public class JungleSounds {

	public static SoundEvent RECORD_SURVIVORS;
	public static SoundEvent SAUROHN_DEATH;
	public static SoundEvent SAUROHN_HURT;
	public static SoundEvent SAUROHN_LAUGH;
	public static SoundEvent SAUROHN_MOCK;
	public static SoundEvent SAUROHN_TALK;
	
	
	public static void init() //Not currently called, doesn't work if used from pre-init
	{
		/*RECORD_SURVIVORS = registerSound("records.eyetyrant");
		
		SAUROHN_DEATH = registerSound("saurohn.saurohn_death");
		SAUROHN_HURT = registerSound("saurohn.saurohn_hurt");
		SAUROHN_LAUGH = registerSound("saurohn.saurohn_laugh");
		SAUROHN_MOCK = registerSound("saurohn.saurohn_mock");
		SAUROHN_TALK = registerSound("saurohn.saurohn_talk");*/
	}

	private static SoundEvent registerSound(String soundName) 
	{
	    //soundID;//SoundEvent soundID = IRegistry.field_212633_v.func_212608_b(new ResourceLocation(soundName));
		final ResourceLocation soundID = new ResourceLocation(References.MODID, soundName);
		return new SoundEvent(soundID).setRegistryName(soundID);
	}
	
	@EventBusSubscriber(modid = References.MODID, bus = EventBusSubscriber.Bus.MOD)
	public static class RegistrationHandlerSound 
	{
		@SubscribeEvent
		public static void registerSoundEvents(final RegistryEvent.Register<SoundEvent> event) 
		{
			init();
			event.getRegistry().registerAll
			(
					RECORD_SURVIVORS = registerSound("records.eyetyrant"),
					
					SAUROHN_DEATH = registerSound("saurohn.saurohn_death"),
					SAUROHN_HURT = registerSound("saurohn.saurohn_hurt"),
					SAUROHN_LAUGH = registerSound("saurohn.saurohn_laugh"),
					SAUROHN_MOCK = registerSound("saurohn.saurohn_mock"),
					SAUROHN_TALK = registerSound("saurohn.saurohn_talk")
					
			);
		}
	}

I ended up initialising my SoundEvents in a method called from RegistryEvent.Register<Item> and storing them in a temporary Map until they're registered in RegistryEvent.Register<SoundEvent>.
