There is no sync between audio and video. Why???

Hi,
I just finished video editing my doc, unfortunately now when I watch it, I get an audio advance compared to the video.
I watch it on a Sony Bravia, NVIDIA Shield TV player and Kodi. To tell the truth I also tried with other software like VLC, but I always get the same audio advance compared to the video.
I have made several interviews and the lip sync absolutely does not exist. I even have an audio advance of 2-3 seconds after the middle of the video.
On the Edius 11 timeline everyting is OK. There is a perfect sync. Can anyone tell me why? I have never had this problem.
Maybe does it depends on the fact that the audio of the narrator's voice was recorded at 32 bit instead of 24 bit? However I configured Edius 11 to 24 bit.
So, after this, I tried to watch that file with the Computer and I get the same audio advance.
Therefore the file itself has audio/video problems after exporting it from Edius 11.
What do you think could depend on?
Thanks for some welcome info.

If this plays out in sync for the whole length of the timeline, something doesn't make sense? What codec are you rendering out to? Is the out of sync offset the same through the whole program? Stay away from some Long GOP codecs for the time being. I would suggest rendering to one of Grass Valley's AVI codecs. Such as Grass Valley HQ or Lossless. If it comes to the worst, you may have to render out the entire audio track as one new .WAV file. And in a new project bring in your out of sync master, create a new timeline and try syncing your new .WAV audio file to the vision. Even if it means you have to cut up and slip parts of the audio track to match up sync with the video bed. Then if necessary fix any gaps or overlaps.

As a remote suggestion, that's the best I can suggest at the moment.
