Sound asynchronous (tvos)

Im runnig Infuse Pro 6.5.5. ATV is connected to a yamaha receiver and tv. My Files are stored on a synologie.
I have noticed, that the sound is asynchronous. When i play the same file with DS Video , the sound is ok. Any suggestions?

Welcome to the forum!

By asynchronous do you mean there’s a delay before the audio starts but is fine after that or do you mean that the audio is not in sync with the lips and actions?

I mean audio is not in sync with actions

How are you connected from the ATV to the receiver and the TV to the receiver?

both with hdmi cables…
