I have numerous google home minis and nest minis in my home and a google router along and three additional points all in excellent range and condition. After many years, google home is now acting weird. My groups won’t play and when it does all speakers in group get statically and phase out. I have to cast from my phone which is a hit or miss. I have rebooted, reset, and unplugged the router along with everything else so please don’t suggest stupid things like move a google mini closer to router! I have replace several google minis with nest minis. I think it might be from an google upgrade. they seem to make it worst with every upgrade. Last night I caught one point upgrading in mid of night which does not fix anything. I cannot find a pattern for it cutting out. I have Comcast cable blast with excellent speed. What else could it be?
Thanks for sharing details about the issue here. I understand the feeling when you're having issues playing music on your Google Home and Nest Minis. A few questions: is the issue isolated when playing music on groups or individual devices? How often does it happen? Is it happening to all songs or music services? What is the current firmware version of your devices?
Let's go ahead and try creating a new speaker group with a lesser number of speakers. Let's see if your devices will have the same behavior.
Let me know how it goes.
