UE4.27 Audio Sync in Level Sequence

Hi everybody,

I know the question has been asked in the past, but with no exhaustive answers.

I have a few Level Sequences, in wich an h.265 video is fired together with one Audio Cue with the speech.

In Editor A/V are perfectly in sync, the problem starts when building for Android and experiencing the app on Oculus Quest 2: video is slightly delayed and the lip sync is completely lost.

I found it incomprehensible that such a tool as UE4 doesn’t have a mean to obtain rock solid sync between Audio and Video streams.

Any new idea on the topic?

Thnks in advance
