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)

The only thing that I can see here that may be causing your problem is the newSound.Volume = sound.Parent.Value * sound.Volume

Sometimes when the volume gets too loud some speakers won't play it because it's out of the range of what the speaker can physically play.

Also it could be that for whatever value it is being multiplied by, it is equalling to a number greater than 10 which is the max volume a sound can be.
