After some more testing I am finding that I still have the audio sync problem. My work around is to restart the AppleTV and then Channels and audio sync is fine.
I will try the following tonight:
- Restart AppleTV choose home pods for audio and start netflix or hulu.
- Close Netflix or hulu and try starting channels to see if audio still in sync.
- Close channels and choose different app like Hulu or netflix to see if audio in sync.
- Restart AppleTV choose home pods for Audio and start Channels.
- Sleep AppleTV for a few hours and see if Homepods are still connected and start Channels and check audio sync.
- Close Channels and choose hulu or netflix to see if audio still in sync.
