Problem with streamer connection

I have a DAC Moon 280 with streamer, the Mind 2.

My problem is that Audirvana doesn’t detect the DAC if it has been used before by the CD player or tidal or qobuz… I have to turn it off, turn it on and don’t connect anything else again. If I do it, the DAC dissapears again and I have to turn it off and on.
I tried another app, Roon, and it’s capable to find it every time (damn it).

Does anyone has the same problem? Did I do something wrong with the configuration?

Kind regards!
