No sound when edit in VariAudio 3

Hi! When I want edit my audio track in Vari Audio (Cubase 12pro) , pitching and other, there are no sound. I tried to do this in on/off Control Room, on/off Acoustic Feedback knob… same problem. My hardware is UR28M and in/out connections very easy. For example I’ve rec/play my tracks on MIX1 outs and when I use CR , its connect by DAW outs. So I think it’s my soft bug. Maybe you can help me to solve this problem. Thanks

hello, could you check in the preferences, if you have the headphone channel active for pre-listening?
