This is most probably related to latency handling. Since PulseAudio API is designed to be remote, it has latency estimation here and there. I actually had no idea how to calculate it, so there are some arbitrary numbers currently.
The first point to look at is /src/apulse-context.c
. Search for string latency = 100000
, there should be four places. I'd try to decrease the values (the are in microseconds) to, say, 10000 us as a start.
Again, I currently have no idea how to do this in a correct way. Some additional research on PA API is required.

I stumbled upon the video test for audio sync: https://www.youtube.com/watch?v=ucZl6vQ_8Uo.
Looks like on my machine, audio is synchronized just fine when using Firefox + apulse.

I've no idea is it still actual, but it's anyway too outdated and can be closed.
