An update - the official release of 15 fixed my intermittent issues with having my Homepod Minis being used by my ATV for audio. It all works great now. On the flip side, I no longer think they can replace my soundbar. The Minis have great sound - better for music by a large margin - but the soundbar is made for TV and does a better job of placing the dialog front and center. You've gotta really crank the volume on the Minis to make the dialog come out as clear as my soundbar - something that's not always preferable. And I have a six year old soundbar - the later ones are likely even better.
Just something to think about.
