Sound script randomly stopped working?

I have a sound script for ambient noises. It's designed to play an audio clip in a seamless loop by always playing a new audio before the current audio ends. It was working perfectly until today and I'm not sure why. Now, the sound doesn't even clone but the print() functions still fire.

This is the error I am receiving:

11:10:33.338 - attempt to call a number value

any ideas? thanks

--getSound
for i,v in pairs (script.Parent:GetChildren()) do
    if v:isA("Sound") then
        soundObj = v
        print("got sound ... " .. soundObj.Name)
    end
end

soundLength = soundObj.TimeLength
print("length = " .. soundLength)

function countDown(sound)
    sound:remove()
end

while true do
    local newSound = soundObj:clone()
    newSound.Parent = script.Parent
    newSound:play()
    print("played new sound .. " ..newSound.Name)
    delay(countDown(newSound), soundLength)
    print("delay fired")
    wait(soundLength-1)
end
