Another report like this was submitted pertaining to last update, but this one has more detail. Chests opening and closing, nether portal ambient and warping sound, blaze idle, damage, and death sound (except for fire noises), zombie pigman idle sound (not testing damage or death haha), zombie damage, idle, and death sound, chicken death and damage sound, horse damage, idle, and death sound, tamed cat and dog idle and damage sound, pick up items, drowned damage sound, piston sound. All mentioned sounds do not play when they are supposed to, haven't tried extensive creative testing yet. I'm sure there are other sounds not working, as I tested all of this in about 10 min on a survival world. 

Also: According to hogwashy on youtube, there are 7 different ghast idle sounds. I'm hearing moan 1 in multiple different pitches, but none of the others.

Edit: Accidentally logged onto creative world so I decided to test a couple things. Anvil falling and placing makes no sound, as well as combining tools with enchanted books makes no hammering sound.

Edit 2: It says this is unresolved but when I logged onto my game this morning a lot of the sounds are now working. Further testing is needed.
