Slimes and magma cubes don't play attack audio

Slimes and magma cubes won't play their respective attack audios unlike Java Edition. It because of a coding bug inside sounds.json.

How to fix: sounds.json is wrong and one of the slime sound events say "mob.attack". Change it to "mob.slime.attack" and it should work. That's it. Only change the sound event name. I put that in a resource pack and the sound works now.
