When piglins/hoglins take damage/die, instead of their own damage/death sounds playing, it is the player damage/death sound.
Steps to Reproduce:
Spawn a hoglin and piglin.
Hit them.
Listen to their sounds.
Observed Results:
The hoglin and piglin do not have their own unique sounds and instead have the player hurt sound.
Expected Results:
The hoglin and piglin should have their own unique sounds, just as they do in Java Edition.
This is now fixed on beta 1.16.0.57.
