#The volume of every villager related sound in this mod
#Range: 0.0 ~ 1.0
volume = 0.0

Doesn't seem to affect the sound at all.

Should be able to adjust volume without having to use the "Block" volume in-game to adjust sound.

mc 1.19
forge 41.0.45
easy_villagers 1.0.2

I have various mods installed, haven't tried without them.

Thanks for reporting this. It should be fixed in 1.0.3
