I think this is related to your system (hardware or software). I had this issue before but fixed after some updates and don't know what exactly causes this issue.
I'm using Archlinux, GNOME/i3wm, OpenJDK 1.8.0_212.
Also mobs can't jump when touching the block.
I have this issue too.
I think I found a solution.
Open this file (or create if not exists)
/etc/openal/alsoft.conf
and change drivers to this
drivers=alsa
