Character Removing event only partially works?

I have a script that kills you and plays audio when you hit it. When the character respawns (AKA when the character is removed and placed at the spawn) it would stop the audio and become invisible. The problem here is that while it works perfectly in studio, the audio doesn't stop in play mode.

script.Parent.Touched:connect(function(p)
    if p.Parent:FindFirstChild("Humanoid") ~= nil then
        local char = p.Parent
        local plr = game.Players:GetPlayerFromCharacter(char)
        if char.Humanoid.Health > 0 then
            script.Parent.Decal.Texture = "insert texture here"
            script.Parent.Transparency = 0
            local s = Instance.new("Sound")
            s.SoundId = "insert sound here"
            s.Volume = 1
            s.Parent = plr.Backpack
            s:Play()
            script.LocalScript:Clone().Parent = plr.Backpack
            char.Humanoid.Health = 0
            plr.CharacterRemoving:connect(function()
                script.Parent.Decal.Texture = "" --works
                script.Parent.Transparency = 1 --works
                s:Stop() --doesn't work, it keeps playing after the player respawns
            end)
        end
    end
end)

Any ideas?
