Script that mutes music isn't working can anyone help?

So basically I have a script for region music for my game and since I have a radio gamepass in my game I want to have a feature where people can mute the background music to hear the radio better. The script does show that it makes the volume of the music in the game to 0 but doesn't actually show a difference ingame. The scripts are

Music = game.StarterGui.SoundRegions.place0
hidden = 1
function RunGui()
if hidden == 1 then 
    hidden = 2
    script.Parent.Text = "Unmute Music"
    Music.Volume = 0
else
    hidden = 1
    script.Parent.Text = "Mute Music"
    Music.Volume = 0.3
end
end
script.Parent.MouseButton1Down:connect(RunGui)

^ mute/unmute button

local SoundRegionsWorkspace = game.Workspace:WaitForChild("SoundRegions")
local Found = false

while wait(1) do

    for i, v in pairs(SoundRegionsWorkspace:GetChildren()) do
        Found = false
        local region = Region3.new(v.Position - (v.Size/2),v.Position + (v.Size/2))
        local parts = game.Workspace:FindPartsInRegion3WithWhiteList(region, game.Players.LocalPlayer.Character:GetDescendants())

        for _, part in pairs(parts) do
            if part:FindFirstAncestor(game.Players.LocalPlayer.Name) then
                Found = true
                break
            else
                Found = false
            end
        end

        if Found == true then
            if script.Parent.SoundRegions[v.Name].IsPlaying == false then
                script.parent.SoundRegions[v.Name]:Play()
                break
            end
        else
            script.Parent.SoundRegions[v.Name]:Stop()
        end

    end
end

^ region music scripts. Anything helps.
