I've been testing with my cluster setup again, in MCU mode, I have 2 connected input streams from different 2 sources.
In the mixed output stream then the inputs switch of location in the layout randomly.
It is also visible in the recording, but that is because it's the same output stream I guess?
Any ideas on how to fix this?
If needed I can share by mail a short video demonstrating the problem
Have you enabled the VAD (Voice Activity Detection) during the room creation? This feature may trigger the input with most active audio occupy the first region of the layout.
