Just upgraded to OS El Capitan 10.11.3 and lost all of my audio setup. How do I restore?

I’m using Roon with a Macbook Pro, Audioengine D1 DAC, and Audioengine speakers. I had everything set up for bit perfect playback, but when I upgraded to El Capitan, I lost the setup and now cannot recall what to do. Below is a screen shot of my audio settings. Hoping for some help to straighten things out.

Thanks,

Mark
