TV OS 15 audio out of Sync via Airplay

[McDin]

Hi there,

since TV OS 15 I have the problem that audio get's more and more out of sync as longer I watch a movie. Moreover the picture skipped some milliseconds back and forth all time and this skip get's the audio out sync.

I also tried with Apple TV to HomePod --> No issues, Also tried with iPhone to Volumio --> no issue.

But the combination of Volumio and Apple TV does not work any more.

Do you have any hint for me? What can I do? Is the problem already in work?

Thanks :)
