Local sound on touched event not working?

local part = script.Parent
local isplaying = false
local soundService = game:GetService("SoundService")
local plr = game.Players.LocalPlayer

local function playLocalSound(soundId)
    if isplaying then 
        return
    end
    isplaying = true
    local sound = soundService.Sound
    soundService:PlayLocalSound(sound)
    sound.Ended:Wait()
    isplaying = false
end

local function onTouch(part)
    playLocalSound(6519564325)
end

part.Touched:Connect(function(hit)
    local h = hit.Parent:FindFirstChild("Humanoid")

    if h then 
        local player = game.Players:GetPlayerFromCharacter(hit.Parent)
        if player then
            if player.leaderstats.Grades.Value > 0 then
                local selling = player.leaderstats.Grades
                local getting = player.leaderstats.Money

                getting.Value = getting.Value + selling.Value
                selling.Value = 0
            end
        end
    end
end)

part.Touched:Connect(onTouch)

Tried to add the sound to a touched event, but the sound just doenst play at all. The output says that the function was triggered tho.
