ROBLOX broke my injure sound script. Anyone want to help me fix it? *Please answer!!*

Recently, ROBLOX fixed the sound bug, BUT in turn, it broke my script. If anyone knows how to get this to work, It'd be much appreciated. By the way, it's a script that plays a sound whenever you get injured.

I get this error in the output window, but I don't know if it has anything to do with my script:

14:46:14.775 - FMOD 36: An invalid object handle was used. 14:46:14.786 - FMOD 36: An invalid object handle was used.

Game:GetService("ContentProvider"):Preload("http://www.roblox.com/asset/?id=155675172") -- Prevents no sound playing the first time the player gets hurt
local lastHealth = {}
function onPlayerAdded(ply)
local f = function (humanoid)
lastHealth[humanoid] = humanoid.Health
humanoid.Changed:connect(function(prop)
if prop == "Health" then
local lh = 0
pcall(function ()
lh = lastHealth[humanoid] or 0
end)
if lh > humanoid.Health then
local sound1 = Instance.new("Sound", humanoid.Parent.Torso)
sound1.SoundId = "http://www.roblox.com/asset/?id=155675172"
sound1.PlayOnRemove = true
sound1:Destroy()
end
lastHealth[humanoid] = humanoid.Health
end
end)
end
ply.CharacterAdded:connect(function (char)
while char:FindFirstChild("Humanoid") == nil do wait() end
f(char.Humanoid)
end)
end

game.Players.PlayerAdded:connect(onPlayerAdded)
for i,v in pairs(game.Players:GetPlayers()) do onPlayerAdded(v) end -- For solo mode testing.
