Audio Capture doesn't work on new MacBook Pro

After using Wirecast for years, when I bought a new MacBook Pro and installed the latest version of Wirecast, I am unable to get audio capture to work — whether a YouTube video, Zoom call, or anything else.

Here are my specs:

  • OS 10.14.1 Mojave
  • Wirecast Pro 11.0.0
  • MacBook Pro 15-inch, 2018; 2.9 GHz Intel Core i9
  • Input source: Screen Capture, with Capture System Audio checked (I've tried both monitor and window settings)
  • Wirecast preference settings for Audio Interface: I have tried System Default, Telestream Audio Capture, and MacBook Pro Speakers with no success

The screen capture shows up, but no audio comes into Wirecast. I replicated all of this on an older MacBook Pro running Wirecast version 10 and the old computer has no problem with the audio capture.

I've read about problems with Apple's new T2 chip, and tried installing the latest Screenflow version (8.2.2) and then uninstalled and reinstalled the latest Telestream Audio Driver within Screenflow. That allows me to successfully capture audio in Screenflow, but does not fix the Wirecast problem. 

Let me know if you need any additional information to diagnose this problem!
