No Sound when using Overbridge / Digitone program

My Digitone and Digitakt work fine when in Overbridge mode and beeing connected to a WIN 10 Notebook using Ableton Live 10 Lite. The Input channels from Digitone giving Signals in the Overbridge Control Center. As soon as I use my Digitone (or Digitakt) in the standalone program Overbridge / Digitone (Digitakt), I still can see signals in the OCC, BUT NO SOUND AT ALL!!!. I am using the latest drivers. Can someone help please?
