enemy monster sound slider is effecting sounds that it shouldn't be and not effecting sounds it should. some examples:
staring at an enderman still makes noise, even when slider is at "0%" (i reported this a few days ago, but it seemed to go unnoticed, so i am putting it here to try and keep these problems together) as someone else reported, xp orbs get muted when said slider is at "0%" (from MC-31432)
the slider also appears to mute the sound played when picking items up from the ground (the pop sound).
if anyone else could do further testing on what is muted or not with this slider, it would be beneficial for everyone. last i checked, items and xp orbs are not enemy monsters, and endermen are. even though endermen are neutral, this slider mutes all other endermen sounds, passive or agressive, so for it to not mute the stare is considered a bug to me.
