@dusx yes, thanks! I've done that and seems to work also with the 'Multi-output device' which is another option (along with aggregate device) in the Audio MIDI setup. I guess I'll have to use one of these!
Bumm! Thanks DusX! That was it. I changed to Multi-Output device, turned on capturing and it works now! Thanks for the tip!
Thank you @Juriaan and @bonemap for your solutions !! I will try it
