Hi Tony, if you don’t need talkback mics, then the way you and your partner tested without BlackHole (and with monitors) is fine.
May I please see a screenshot showing what it looks like when you try to use BlackHole to ferry audio from your standalone app to FarPlay? In particular, I’d like to see the audio device settings in your standalone app, the Preferences > General Options settings in FarPlay and, if you’re using an aggregate device, the settings for your aggregate device in macOS’s Audio MIDI Setup. Thank you.
