Question / Help Audio / Video sync issues


New Member
I don't think this is very related to Windows or Mac, I think it applies to everything.
Issue is, - when I live stream against Facebook, the video from time to time, is off if you look at audio/video sync (lipsync).
What is the main reason for this?
What can one do to make the video in better quality?
Is it related to software settings? Hardware requirements?

I usually stream at 2500 bitrate.
