Homepod Setup Failure - Homepod making no sound signature or code

Homepod was setup with Apple TV when it stopped putting out sound. Neither via Apple TV or iPhone. During fault finding, I factory reset the Homepod. When trying to setup Homepod, I use my camera to find the Homepod, but then it doesn’t give any sound signature and also doesn’t read any code when selecting to do it manually.
