I am connected to my 16.4.2 Ai mixer using Firewire into a late 2011 Macbook Pro running High Sierra. The audio input device on Streamlabs see my Presonus mixer, indicates some input signal, but I can't monitor it or hear it in the OBS program or from the board with the digital button selected. The needs are two-fold: we want to live stream our band, and we need to hear an actual monitor mix in the room. Every video that seemingly explains the connection is using a newer board or has a virtual software that seems to recognize the input. If I need to re-route an aux mix to channels 1& 2 for a stereo output that OBS can see, how do I do that?
Very confused over here. Any help is appreciated. Thank you in advance.
