RME ADI-2 DAC fs USB and ROCK Core help with settings

I installed Rock on NUC 8I5 BEH I want to teach RME connected directly via USB to play but he is silent. Can’t set up. Help with settings

Try shut down for both NUC and RME, and then restart for both.

Have you selected the DAC in Settings then Audio. My RME ADI-2 DAC fs showed up right away when connecting it.

I turn on the NUC and then the tablet and ROON cannot connect to the core. I turn off and turn on WI-FI everything is located at once. How can I fix this.
