Question / Help Audio lag with Skype NDI

Hello everybody!
I'm new to OBS so, I'm sorry if I'm asking something stupid.

Yesterday I was online with my first live stream on Facebook. I had two guests, with Skype NDI (it was a group call). Everything was fine.
When the 4th guest came in, the audio suddenly became very delayed, but just for two of then. And it was like this the entire live.

How come? Is it a Skype problem? A OBS bug? :-)

Here's the LOG

You cut out all the useful portions of the log.

It would not surprise me that 4 NDI feeds was overloading your CPU, on top of running OBS.

You cut out all the useful portions of the log.

It would not surprise me that 4 NDI feeds was overloading your CPU, on top of running OBS.
Click to expand...

So maybe the problem is just an overloading of the CPU?
I tryed to change the "sync" setting in the NDI options from "network" to "internal" but the audio is completely out of sync.

And I also noticed that the audio source is the same of each skype user. So the 1 first one got the "audio" of the other 2 o 3 users. And that's quite bad but I guess there's no solution.

Is there a way to have more than 2 skype user without getting problems like this?

Audio isn’t synced with video: this happens because you either are using your own Skype NDI video or your webcam, with your local microphone. Audio travels faster than video, so there’s an offset you need to program in OBS. Mine is about 200ms.

The problem I'm getting is that the audio starts out synced but lags over time. I can bring it back by selecting a different ndi sourve then selecting the right one.
