Some sounds are not playing

Guys, we all know that people wait for caves&cliffs update, it is obvious.
But despite that, you should really take your time on making a new "Optimized" versions.

The problem is, that in the newest version of minecraft, some of the sounds are gone.
For example: Diving sound do not play, Coming out of underwater sound does not play. Now i need to create a category: Sounds of portal. Almost every sound is gone, except the ambient noise. End teleportation sound is gone too.

Well, i think there's much more sound bugs in this version.
Please, do me a favor. Check the new versions for bugs, ok? Let your players play new versions without issues. I love you guys for community that you created and for sandbox game, that you are updating.

This game is making me fly away from real life for a moment.
