Script I made where when a button is pressed, a sound is heard only works sometimes?

So I made this little button GUI that will grow and shrink a bit when clicked on, as well as make a sound. While the former works, it only makes the sound like 80 percent of the time... is there some hidden rule about sounds that I don't know about?

local debounce = false
local p = script.Parent.Parent

function anim()
    if p.Position.Y.Scale >= .75 and script.Parent.Parent.Parent.Parent.Clicked.Value == true then
        p:TweenSizeAndPosition(UDim2.new(.32, 0, .17, 0), UDim2.new(.49, 0, .74, 0), 'Out', 'Linear', .05) --Making the button slightly bigger when clicked
    end
    local sound = p.Parent.Parent.Parent.Parent.Sound.Button.Button1 --I have a template sound stored so that I can edit it as I wish
    local newSound = sound:Clone()
    newSound.Parent = script.Parent
    newSound.Volume = sound.Parent.Value * sound.Volume
    newSound:Play()
    wait(.05)
    if p.Position.Y.Scale <= .75 and script.Parent.Parent.Parent.Parent.Clicked.Value == true then
        p:TweenSizeAndPosition(UDim2.new(.3, 0, .15, 0), UDim2.new(.5, 0, .75, 0), 'Out', 'Linear', .05) --Shrinking it back down .05 sec later
    end
    repeat wait() until newSound.IsPlaying == false
    newSound:Destroy() --Destroy the sound when it's finished playing
end

script.Parent.MouseButton1Up:connect(function()
    if debounce == false then
        debounce = true
        anim() --Firing the above function
        script.Parent.Parent.Parent.Parent.Click.Value = 1
    end
    repeat wait() until script.Parent.Parent.Parent.Parent.Click.Value == 0
    debounce = false
end)
