About a year ago my HomePod started making some random clicks. I thought it might be something to do with electrical interference. When I first contacted Apple it was two months after my Applecare expired and all stores were closed due to COVID. Then about a month after I contacted Apple it sounded like my HomePod soiled itself (See video). When I finally made an appointment at the Apple Store and was told by the Genius my only recourse was to sell it or throw it away. The non-warranty replacement cost as much as a new one! Now I have a $300 paperweight, would have thought there was some middle ground. Not sure how widespread it is but there is definitely a problem. My advice if you hear a click get a hold of Apple immediately.
