How do I fix this death script?

This is in a server script:

game.Players.PlayerAdded:connect(function(player)

	repeat wait() until player:FindFirstChild("leaderstats")
	local lives = player.leaderstats.Respawns

	player.CharacterAdded:connect(function(char)
		char:FindFirstChild("Humanoid").Died:connect(function()
			lives.Value = lives.Value - 1

			player:FindFirstChild("Backpack").Death:Play()
			children = player.Backpack:GetChildren()
			for _,v in pairs(children) do
			if v:IsA("Sound") then
			v:Stop()
			v:Destroy()

			end
			end
		end)
	end)
end)

What I'm attempting to do here is two things: Remove one life from the player when he dies, as well as play a "death" sound. The problem is that this rarely works online for some reason. I tried a local script too but it doesn't seem to work. It could be a problem with the script or there might be some other way to do this that I'm not aware of. Any ideas?

For the sound aspect, try adding a wait of however long the sound plays for. From my beginner standpoint it appears as soon as it is told to Play it is told to Stop.
