When using phosphor, may audio seemed to be delayed. I'm using lithium, minihud and rougly enough items on 1.16.1. My OS is ubuntu 18.

Following` squid's suggestion seems to have fixed it. Either I should've tested more throrougly (I tested like, 3 times) or it's pulseaudio being finnicky. You decide if you should close it or not.

by default you can run into strange issues like this... Minecraft in particular falls victim on my system

JellySquid
high-priority = yes
nice-level = -11

realtime-scheduling = yes
realtime-priority = 5

default-fragments = 2 
default-fragment-size-msec = 4

you can modify your /etc/pulse/daemon.conf  to include these entries

I'm going to close this as it's extremely unlikely Phosphor (or any of my other mods) have anything to do with this. More likely than not, just a poor default configuration for your system.
