HomePod 2 randomly playing music

I have a stereo paired set of HomePod 2 speakers that are primarily used in conjunction with my AppleTV for movies, television, etc. about a month ago, they started randomly playing music without any prompting from me. This can happen at anytime (and I've had to get up in the middle of the night multiple times to hit the top of a HomePod to stop the music playing. Sometimes it begins with Siri saying that she's found a station that I'll like, sometimes it just starts playing. It's already happened twice while I've been typing this.

I disabled the listening feature on the HomePods months ago so Siri isn't hearing requests from me. The only thing that I can think of that might have something to do with this is that I often work on my 15" M4 MacBook Air in the same room as the speakers and I've got my iPhone 17 Pro in here, too. On occasion, my M4 iPad Pro is in use as well. Could one of my other devices be triggering the speakers even though none of them are playing music when this happens?

Does anyone know how I can stop this?
