Hi. I'm using OBS with MAC. Using Apple's MIDI by setting up an aggregator for sound output, my desktop output now runs through the OBS app. In the audio mixer I see all of the levels reflecting my Microphone and desktop audio. The problem is even when I go to advanced settings and set the monitor to my headset I still can not hear anything in the Mixer. I do interviews so I need to hear the audio play and its volume in real time as I adjust the levels of different audio sources as I go. I want to hear exactly how the audio will be streamed or recorded. It seems simple enough to setup the monitoring device in OBS settings - yet when I do so nothing happens. Open to any suggestions! Thanks!
