Hello rebeka,
I found that my iOS device works now.
But on my MacOS, if I enabled both “System Output” and “Apogee Duet USB”, Roon says “No audio devices found”. Then when I disabled “Duet USB”, “System Output” shows up and the music plays.
If I enable other devices like “Built-In Line Output”, It will be selectable in Roon. But If I re-enable “Duet USB”, It is not shown in Roon. Although the music still plays through “System Output”, the playbar and other track info freezed. (next track and prev track still works) .
I have uninstall/reinstalled the driver of Apogee Duet USB, still the same.
Here is the log file if needed:

BTW, I can not backup my database now. Roon says: Error backing up database.
thank you,
Yasmina
