How To Play a sound via a script ( not local?)

local RepStorage = game:GetService("ReplicatedStorage")
local KGFolder = RepStorage:WaitForChild("KGRemoteEvents")
local ActivateRemote = KGFolder:WaitForChild("SharinganActivate")
local ServerStorage = game:GetService("ServerStorage")
local KGItemFolder = ServerStorage:WaitForChild("KG_Folder")
local SharinganFolder = KGItemFolder:WaitForChild("Sharingan")

local function ActivateSharingan(plr)
	if plr.KGStore.KGActive.Value == true then
		if plr.Character.Head:FindFirstChild("GenkaiDisplay") then 
			plr.Character.Head.GenkaiDisplay:Destroy()
			SharinganFolder.SFX.SharinganDictivated:Play()
			plr.KGStore.KGActive.Value = false
		end
	else
		SharinganFolder.Stuff.GenkaiDisplay:Clone().Parent = plr.Character.Head
		SharinganFolder.SFX.SharinganActivated:Play()
		plr.KGStore.KGActive.Value = true
	end
end

ActivateRemote.OnServerEvent:Connect(ActivateSharingan)

Get the Sound Object and do:

local sound = script.Sound
~~your event~~
sound:Play()

It depends where you sound is, what works for me is if you put the sound in workspace and put a server script in workspace and then write this in the script

local sound = game.Workspace["insert sound name in here"] --insert the sound name in the " "
sound:Play()

I hope this helps!
