Absolutely new to OBS. No audio in or out. Tried setting up audio following instructions from a number of sources (forum posts, YT videos, Blackmagic manual). Setup different scenes, different combinations of sources, monitoring selections, different audio settings, and still no audio. No movement in audio mixer meters. Setup: Blackmagic ATEM MIini. I would like to use this device as the audio and video input device. I'll output to wherever I need to for streaming or recording. Audio works in Windows (10) Media Player, Pro Tools, and Sibelius (PTs and Sib audio I/O to Focusrite Scarlett 2x2 -- I DO NOT use this device in OBS because PTs needs to use it exclusively). I've read a number of posts and tried those solutions to no avail. Truly at a loss. Getting audio assistance would be most appreciated.
