Overbridge keeps sending audio to MacBook Pro (2019) speakers instead of selected laptop audio output

When I have my Digitone Keys hooked up and working with Overbridge as standalone on my MacBook Pro (2019) Touchbar there is no way to channel the audio from the Digitone Keys to my headphones connected on my laptop even though it is available in its System settings => Audio as choice for output. Whatever I choose, the Digitone Keys audio keeps playing on the laptop speakers. That’s funny.

Anyone with similar issue? Would be glad to hear.
