Apple TV 4K to tvOS 15 wireless audio sync issues

I updated my Apple TV 4K to tvOS 15 and now, all my *Apple* devices will not sync audio wirelessly. This includes AirPods, AirPods Pro, AirPods Max. Doesn’t matter what I’m watching, or what app/service I’m watching, the audio is out of sync. I tried using the calibrate wireless audio feature in the settings, but when I try it defaults the audio output to TV speakers which doesn’t have any problem…because it’s wired! So not sure what wireless audio sync is good for if it’s only checking if wired audio is synced. The closest fix I could find, but it’s still really out of sync, is setting my video output to 4K Dolby Vision and turning off Match Content and Frame Rate. The problem with that is the TV menus are not in HDR, so if I change my TV’s input and then go back to the Apple TV input channel, the screen starts flashing green and static until I power reset both the TV and the Apple TV. Everything worked flawlessly before the tvOS update…BUT, I have the new Apple TV 4K which doesn’t have a USB-C port…so I can’t downgrade it back to 14.7. Anyone else with similar issues?? I will add that when using my HomePod stereo pair as the default output, the audio seems to be in sync, but if I try to calibrate wireless audio to the HomePods, the Apple TV changes the audio output to TV speakers. And even though it seems to by synced with HomePods, if I temporarily change audio to headphones it goes completely out of sync. I’ve also tried defaulting Video output to every available option and tried wireless audio, still out of sync.
