Hey,

I came across an interesting bug:
If you put the audio of a video on BusA (or any other), then put that bus on the master, the vMix caller can't hear that master. Only if you put the audio source for the switching guest on BusX will it hear this sound.

Steps for tracking:
1) Create an input with sound
2) Set the audio input to BusA
3) Set BusA to Master
4) Create a vMix call and set the audio source to Master
5) The guest does not hear the audio from the master
6) When setting to BusA the guest hears the audio

Best regards and thanks in advance :)
