why does my homepod make cracking sound on idle?

Hey tung2323,

If we understand correctly, the HomePod is making a crackling noise while it is idle.

Does it make this sound while playing music?

"Press the top of HomePod to reset it

If you can’t remove HomePod from the Home app, you can press the top of HomePod to reset it to its factory settings. Here’s how:

1. Unplug HomePod, wait 5 seconds, then plug it back in.
2. Wait 5 seconds, then touch your finger to the top of HomePod and hold it there.
3. The white spinning light will turn red. Keep your finger down. 
4. Siri will say that your HomePod is about to reset. When you hear three beeps, you can lift your finger.

If you still see HomePod in the Home app after you reset it, then you'll need to manually remove it from the Home app."

Hey tung2323,

Thanks for the update. Since it is still making crackling sounds when not playing music, it sounds like it may be wireless interference.
