I'm running OBS with an ATEM Mini Extreme. The issue we have is a few people can only hear our livestream if they put in earphones. They can hear audio that comes from the OBS input but not the input from the ATEM. Most people hear everything OK. They have the same problem with play back after livestream is over. I think they are all Android users. We did not have this problem when we used the Blackmagic Design Intensity Shuttle. What could be causing this?
