HomePod mini listens for Siri invocation anytime volume is adjusted on AppleTv

Ever since I updated all my devices to OS26, my pair of HomePod mini have been behaving erratically. Whenever I adjust the volume on the AppleTV that the HomePods are connected to, they *listen* as if I had said, “Hey Siri.”

Additionally, the duration of this “listening” behavior is significantly longer than usual (approximately 90 seconds).

I restarted the HomePods via the Home app, but the same behavior occurs.

**(By “listen”, I mean the speaks lower the media volume down really low and create an echo/reverb effect).
