I am currently setting up my a new M1 Mac for streaming using OBS Studio and was surprised that capturing audio from multiple sources other than the mic required this. It is one of the few things I have found that “just works” on a PC compared to a Mac. I am glad this exists, thank you!
did you try setting up an aggregate device in Audio MIDI Setup? I do a lot of audio work with Macs, and even use blackhole on occasion, but typically something as simple as capturing audio from multiple sources can be done natively with a simple aggregate device.
Where would I go to find info on setting this up natively? I've looked before but clearly missed something.
