Replacing audio in video stream

In Cubase, I’m trying to replace the audio in a video file (mov-file). The mp3 audio mixdown works fine and so does the video clip. But when I replace the audio in the video file (using Cubase’s “replacing audio in video stream” feature), there’s no sound at all. Does anyone know how to solve that?


What Cubase version do you use?

This function is not available since the new video engine (Cubase 9.5.x and Cubase 9.0.40).

I’m the older version, it works as Export Audio Mixdown (if I remember right). So you have to stop the left and right locators.
