different containers and different types of films sd/hd types can cause different delays, that would be quite a mountainous task to get the delays right for everything and even then, its still broken and not right.

at this point the simple solution would be to scrap sync to display and make it so people can use reclock as the audio renderer. The only problem with that solution is their doesn't seem to be a similar thing for linux

I too have tried all the aforementioned suggestions and have same the problem with audio sync with 24hz material that everyone else is getting. (for me i need a -200ms delay to sync correctly)

There is a simple fix that would work for everyone:

Currently you can set the delay in the menu to say -200ms.... Then you can check the option that says: "Use this as default for all videos"

All that's needed is for there to be multiple options. For example

"Use this as default for all 24hz videos"

So the theory would be that if it detects source material with 24fps, then it applies the user set delay. If the source material is anything else (eg non 24p) then it will not apply a delay (thus not affecting 50hz or 60Hz video)

I'm sure this would work? I'm not a programmer just applying logic in order to find a solution to this very frustrating problem.
