Direct Offline Processing NO Sound

There is no sound in the window Direct Offline Processing. I can not listen to the result. Only by closing the window and returning to the project I can listen to the modified clip.
Nuendo 11.0.20, MacOS 10.14.6, Output-Dolby Audio Bridge.
Please tell me how to find and fix the current problem.

You really should read the manual on using the DOP and monitoring
this is difficult to understand and very flexible to configure…

first thing would be, to look what is your monitoring output now… that’s where the pre listening signal is send to

Thanks, your answer helped me. Configured monitor output and it worked
