We broadcast a lot of sports and from different events at the same time.

We have the need to send the Master sound back to each arena in the right headphone and all talkback sound back in the left channel, otherwise drown Talkback in all sound sent out from the master.

We keep in touch with all the different commentators in all arenas at the same time and can jump between them when there are goals or other interesting events we want to broadcast.

We use vMix advance in every arena

However, we do not succeed in dividing the sound, even if we run different subgroups or change the sound matrix. these sounds are converted to Mono and are heard equally in mono in both headphones at the commentators.

We do not use the SeparatMono setting for these always control the sound to Master out and it does not work as we need several AudioBus at the same time.

Where does it go wrong or is there a limitation on the vMixCall receiver that all sound becomes mono?

We have also tested with the Force Stereo setting in vMixCall without success.

first you must get sure about your audio busses

Bus M - Broadcast out in each arena
Bus A - Broadcast bus external arena to main broadcast center
Bus B - Talk Back bus between arenas
Bus C - "Signal Bus" to main broadcast center

In each arena there is a sound file routed in the vMix set up to Bus C.
Then you can write a small script monitoring audio level of bus C.
If there is a signal on Bus C (which nobody has to hear in first place) you can display a kind of sign
(image, Text, whatever) on the preview "News" (e.g.)

I made something similar with a trigger on "CallConnected",
which gives me a visual sign "there´s somebody"

But... it is difficult without knowing the definit set up,
but maybe its a hint, what you could do...
