Slime blocks do not make placing or destroying sounds when 'hostile creatures' volume is off. This is likely because it now makes the same sound as hurting a slime.
To replicate:
1. Turn 'Hostile Creatures' volume to off in the music and sound settings.
2. Place/destroy a slime block and see it doesn't make sound.
