Continual popping sound on homepod

Was the software recently updated? Seems there are several posts blaming that as being the cause , which you can’t undo.

Is it happening while airplaying from an app? See if that’s the cause by trying something else

Try moving the HomePod to another spot to see if it’s picking up an interference from something.

Or Reset HomePod

Hello,

Have you tried restarting your HomePod?

Unplug HomePod's power lead > Wait 30 seconds > Plug HomePod back in.
