There's no way that is a parity issue, I can't remember ever not hearing sounds in Java before..
Thank you to whoever marked my report as a duplicate, this is not sarcasm.
Nevermind, it appears to happen when going to the overworld too, just, only when using a command block to run it.
@GoldenHelmet I fail to see the inconvenience of a block doing what it's supposed to do when broken while in creative.
Let's say you have a block meant to explode so you place it to remove more blocks and it doesn't work. The player would be confused by this behavior and think the addon is broken.
Some blocks also use this event to figure out what items to drop, for storage-related reasons, like custom jukeboxes.
