No Audio Devices Found with 1.2 [fixed]

Support
1

OS X 10.11.4 with Roon 1.2. After the upgrade, Roon is showing “No Audio Devices Found” but all of the devices are in the Settings screen. I tried changing settings and even blowing away ~/Library/Roon/{Database,Settings,Cache} but I get the same problem.

At startup, the following is in the Roon log:
