I put this script in StarterPlayer>StarterCharacterScripts and it isn’t working. It used to work before sounds were moved from the Head to the HumanoidRootPart, which I tried to convert. The script is basically supposed to change the ID of the running sound and pitch the other avatar sounds so they sound unique.
local walk = script.Parent.HumanoidRootPart:WaitForChild("Running")
walk.SoundId = "rbxassetid://2653887376"
walk.Volume = .3
walk.PlaybackSpeed = 1.8
local splash = script.Parent.HumanoidRootPart:WaitForChild("Splash")
splash.PlaybackSpeed = .78
splash.Volume = 0
local swimming = script.Parent.HumanoidRootPart:WaitForChild("Swimming")
swimming.PlaybackSpeed = 1.1
local jumping = script.Parent.HumanoidRootPart:WaitForChild("Jumping")
jumping.PlaybackSpeed = .75
jumping.Volume = .4
local landing = script.Parent.HumanoidRootPart:WaitForChild("Landing")
landing.PlaybackSpeed = .82
