I use a pair of homepod minis in conjunction with the internal speakers in my TV. When I press the mute button on my Siri remote, only the TV speakers respond (through the IR on the remote I imagine). The homepod minis continue to function as normal. Is there a way to get the homepods to respond to the mute function as well, simultaneously?
I think you'll find that it's working as designed. Since your default audio output is set to be your TV's speakers, when you select the HomePod minis as supplemental AirPlay speakers, the volume control focus remains on the default audio output (the TV). Consider that most AirPlay connections are for listening in another room (hear the game while grabbing a snack in the kitchen, etc.), and most AirPlay speakers have their own volume control.
OTOH, if you deselect your TV's speakers (using the AirPlay config via Control Center), and select only the HomePods, your mute button will function. Better yet, if you set the HomePod minis as your default audio output via Settings > Video and Audio > AUDIO: Audio Output > DEFAULT AUDIO OUTPUT: [Select HomePods], I believe you'll actually get better Home Theater sound from the HomePod minis than they can do via a simple AirPlay connection.
I realize the 'minis don't support Dobly Atmos in this mode as the original HomePods do, but it seems their "computational audio" capability benefits from multichannel sources - better movie dialog from the center channel for example. NOTE/disclaimer: I'm speculating here based on my brief impressions from casual testing -- I don't have inside implementation info from Apple (nor am I aware if technical implementation details have been published).
I happen to have a decent soundbar under my TV and a stereo pair of HomePod minis in an adjacent area (open floor plan). I occassionally play music on both the HomePods and TV/soundbar at the same time. When I do this, I agree that unified volume control is a bit of a pain.
However, if not for the soundbar, I would place the HomePods on either side of the TV and set them as the ATV4K's default audio output (using the [e]ARC features of the ATV4K & TV), and just ditch my TV's internal speakers.
