Why does my HomePod cut out when the volume gets louder

Hello Faihst_dxb,

We would like to see how we can help you with your HomePod minis unexpectedly shutting off. Let's start by manually checking if you have any updates avaiable for your HomePod minis with the steps in this link: Update HomePod - Apple Support

1. "Make sure that your device is updated to the latest version of iOS, iPadOS, or macOS. 
2. Open the Home app. 
3. Tap or click the More button , then Home Settings  > Software Update.
4. If there's a new update, select Update. If there isn't a new update, you can select HomePod to turn on automatic updates and get the latest software automatically when it's available. Software Update also tells you if your HomePod is already up to date, and shows you the installed HomePod software."

Should the issue persist, reach out to Apple directly for further assistance at: Apple Support

Cheers!
