Try installing Source-Nexus to use the virtual devices it installs
by default:
- Download Source-Nexus from the user dashboard.
- Uninstall Source-Connect.
- Reboot your computer and run the Source-Connect installer.
- Before launching Source-Connect again, make sure you set your Mac System Preferences Sound Settings to input “Source-Nexus A” and output “Source-Nexus B”.
- Open Source-Connect again.
- If none of the above works, create an aggregate device with “Source-Nexus A” as the input and “Source-Nexus B” as the output, and set that device on your Sound Settings.
