HomePod stereo pair will not sync volume

Two HomePods stereo paired and using apple 4K tv. Inevitably, for over a year I’ve had this problem, lose sync with VOLUME only. For example, after a fresh restart and update to the max of all the equipment in question, everything works for a few days and then suddenly, turn on the tv and attempt to control the volume. ONE speaker obeys my commands, one does not. The disobedient speaker is not mute, just not responsive. Sometimes it gets locked at a low volume and sometimes high. So it’s infuriating when you need to turn the show down but one speaker is locked at 70%. Alternatively, when wanting the full impact of two HomePods, one is defunct and playing at 20%.

I have heard rumor it’s a WiFi issue. How I am supposed to fix that I have no idea. I’m pretty sure it’s a software issue.

of Note, both speakers work perfectly when not linked together. Separately all is well.

how is this bug not fixed yet?? I saw at least 30 others in a similar thread from 2020 had this issue. It’s almost 2022 let’s be done with this mess. Please help.
