no sounds in the new snapchots.

So my sounds dont work in the sanpchots 18w43c, 18w43b and 18w43a But they do work in 1.13.2 and every other version, so i dont know if this is a bug or something else. But i hope this gets fixed as soon as possible. "update" the New snapchots 18w44a-18w46a didn´t help at all. But i realized that in the game outputs it says "[client threat/warn] missing sound event for" for all the sounds in minecraft.

Finally in the version 18w50a the sounds work again!!!!!!

Thank you for helping!
