I have found if I manually copy ZoomAudioDevice.driver from my application bundle to “/Library/Audio/Plug-Ins/HAL” and then restart CoreAudio
sudo launchctl stop com.apple.audio.coreaudiod
sudo launchctl start com.apple.audio.coreaudiod
And then launch my app and share audio, I no longer receive the Error: 3 issue and audio share works.
Obviously this isn’t something a customer would be doing.
But I am still unsure of how to achieve this as MacOS requires root access to install to that directory. Also unsure if this is something the SDK should be attempting to do or if it is something our client is supposed to do.
