HomePod automations with audio do not work
I can manually get my HomePod Mini to play audio. But no automations involving audio work - and clicking the "test automation" button does not work either.
That is to say, I cannot get an automation to start, resume or pause audio. And I cannot test any automations doing those things. This applies to Ambient Sounds, and to everything available via Apple Music (I have an Apple Music subscription).
I also have an IKEA/Sonos speaker set up in HomeKit and all audio automations do work on this speaker.
My HomePod Mini is running tvOS 17.5 (21L569) with no updates listed as available under Home Settings > Software Update. I have been setting up the automations on an iPhone 13 running iOs 17.5, and also tried testing them on a MacBook Air (2018) running MacOS Sonoma 14.5
Any idea why this would be happening?
