There is no recall and this model was discontinued, so no warranty.I had one do that and there is a solution that might work but as you’ve said this model can be very hard to reset or even set up again.so it’s do it at your own risk! I’d also question as to why your HomePod is getting very hot? It’s best if you can plug it directly into the wall and if you must use an extension cord don’t let it share this cord with other higher voltage items. Never daisy chain cords. Changing how I plugged mine in reduced the overheating issue.
To fix the sounds:
first start by unplugging HomePod for over 24 hours
plug back in and do the following:
- Unplug HomePod or unplug the power adapter for HomePod mini, wait 10 seconds, then plug HomePod back in.
- Wait 10 seconds, then touch and hold your finger to the top of HomePod.
- The white spinning light will turn red. Keep your finger down.
- Siri will say that your HomePod is about to reset. When you hear three beeps, you can lift your finger.
After you reset HomePod, you can set up HomePod again.
