How do i make it where when you run it plays a sound but when you stop moving it would stop playing?

So i got a run script that displays a run animation and i dont know how to make it play a sound. how do i make it play the sound when you run? what i got so far is ~~~~~~~~~~~~~~~~~

local Player = game.Players.LocalPlayer
	local Character = workspace:WaitForChild(Player.Name)
		local Humanoid = Character:WaitForChild('Humanoid')
		
local RunAnimation = Instance.new('Animation')
RunAnimation.AnimationId = 'rbxassetid://2543615157'
RAnimation = Humanoid:LoadAnimation(RunAnimation)

Running = false

function Handler(BindName, InputState)
	if InputState == Enum.UserInputState.Begin and BindName == 'RunBind' then
		Running = true
		Humanoid.WalkSpeed = 70
	elseif InputState == Enum.UserInputState.End and BindName == 'RunBind' then
		Running = false
		if RAnimation.IsPlaying then
			RAnimation:Stop()
		end
		Humanoid.WalkSpeed = 16
		sound:Stop()
	end
end

Humanoid.Running:connect(function(Speed)
	if Speed >= 10 and Running and not RAnimation.IsPlaying then
		RAnimation:Play()
		Humanoid.WalkSpeed = 70
		sound:Play()
	elseif Speed >= 10 and not Running and RAnimation.IsPlaying then
		RAnimation:Stop()
		Humanoid.WalkSpeed = 16
		sound:Stop()
	elseif Speed < 10 and RAnimation.IsPlaying then
		RAnimation:Stop()
		Humanoid.WalkSpeed = 16
		sound:Stop()
	end
end)

Humanoid.Changed:connect(function()
	if Humanoid.Jump and RAnimation.IsPlaying then
		RAnimation:Stop()
	end
end)

game:GetService('ContextActionService'):BindAction('RunBind', Handler, true, Enum.KeyCode.LeftShift)

Hi superpichufan_57,

You might want to try using GetPropertyChangedSignal("MoveDirection")

With this you can check how fast the character is moving and act accordingly

Humanoid:GetPropertyChangedSignal("MoveDirection"):Connect(function()
	if humanoid.MoveDirection.Magnitude > 0 then -- if they are moving
		if sound.IsPlaying == false then -- if it isn't already playing
			sound:Play()
		end
	else
		sound:Stop()
	end
end)

Of course you could tailor this to your specific situation. Let me know if this helps.
