Audio sync - behind

Audio sync issue is terrible and seems to get worst after each update. I switched to HDHomeRun app on the 4K AppleTV and audio syncs fine so I know this is the issue with channels app.
Any solutions?

Which Apple TV? And audio driver?

I want to chime in here and say I experience the same thing. When I reset the wireless audio sync in the ATV settings, it works fine again. The issue for me is that I use headphones a lot at night, so leaving the audio sync not calibrated is not a good long term option.

Latest 4K model.

Has there been any guidance on this? I have multiple Apple TV 4K models running iOS 18.1 and the audio is out of sync unless I choose the legacy audio driver.

Second this. New user as of today, everything's perfect except for a noticeable audio delay when using the default audio driver. Switching to legacy mostly fixes it thankfully
