Simple! Use a localscript to play the sound. You can also play it in the PlayerGui or simply move it to ScreenGui and when a server starts it will do it for you. I have rewrotten the script so that the sound will work if it is in the players PlayerGui. Simply drag it in to ScreenGui and let it play.

local db = true
script.Parent.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") ~= nil then
        if db == true then
            db = false
            script.Parent.Transparency = 1
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)
            player.leaderstats.Coins.Value = player.leaderstats.Coins.Value + 5
           player:WaitForChild("PlayerGui").Sound:Play()
            script.Parent.Transparency = 1
            wait (13)
            db= true
            script.Parent.Transparency = 0
        end
    end 
end)
