How can I stop my HomePod from auto-playing?

Hi,

A few days ago, my HomePod started to play music on its own when I was out of my home.

So I went to pause the music and the touch screen wasn’t working… I plugged it off and then I restored it.

The touch screen wasn’t working again when I touched the centre of the screen, but it started working when I touched the corner of it. I said, “ok i don’t care a lot about touching, so I was okay with it.”

The problem started again yesterday with the music that was playing on its own and at night WHEN I WAS SLEEPING!

I thought I was in a Paranormal Activity movie…

How can I solve the problem? I saw on Reddit some users that had the same problem, so I’m not the only one… and of course, my Apple Care+ expired last month.
