After few days of testing... It really looks like the audio offset is caused by the manual side projection.
Or rather said the offset is fixed by the automatic front projection. Addon: I've recognized that the offset gets worse with more angle of manual side projection (i.e. ~10° angle = 0,5 sec delay / ~40° angle = 1,5 sec delay ... just an experience / feeling, no testing with equipment). And completely fix (with built in apps / no fix at all with cast function) by automatic front projection. Which is quite sad, because I really need manual side projection.
- cast: offset with side projection and front
- built in: offset by side projection only
No offset: built in app with front projection
Is there any possibility to talk to your tech team to investigate and probably find any solution to fix it? Any SW update for angle correction? Or maybe add a function to manually change the audio offset?
Long text, I know. But I wanted to give you as much information as possible.
Again, thanks a lot. Besides that I am really happy with your Beamer and I hope that you may be able to fix it.
And I hope you all stay safe and healthy
