variaudio no realtime sound with editing

hi, seems my variaudio realtime editting doesnt work. Not even with headphone settings; just no sound at all with editing. The playback works great but not the variaudio real time edtting. Someone an idea? (also checked control room on /off… no results)

It´s not simply About Control room on or off, but about configuring it correctly.
Next Things to check:
-Acoustic Feedback in the Editor is on, and the editor preview volume fader is up
-Preview is not routed to the phones out in preferences.
