Lava burning items or XP orbs sound muted when "Friendly Creatures" slider is turned off

The bug

The burning sound when items or XP orbs are destroyed in lava is muted when you lower the audio slider associated with Friendly Creatures to off.
It would make more sense if this sound was associated with Ambient/Environment since it's not a creature sound.

Code analysis

Based on 1.11.2 decompiled using MCP 9.35 rc1

The classes EntityItem and EntityXPOrb do not override the method net.minecraft.entity.Entity.getSoundCategory() which returns NEUTRAL as sound category.

Important: It is very likely that this affects multiple other entities such as paintings, item frames, minecarts, etc.
