Quick testing suggests that ACE_isUnconscious isn't changed when killed. I've found a location where this returns inconsistent behaviour:

ACE3/addons/nametags/functions/fnc_initIsSpeaking.sqf

Line 44 in cb40c8e

([_unit] call acre_api_fnc_isSpeaking) && {!(_unit getVariable ["ACE_isUnconscious", false])}

Do we want to switch to EFUNC(common,isAwake) or lifeState == "INCAPACITATED"? I.e should we display sound waves above dead players when they are talking in spectator? Imo it shouldn't and we should switch to EFUNC(common,isAwake).
