Unable to open audio file for playback 2

I can only show you the Windows version of Audirvana 3.5, but I assume it will be the same on the Mac.

Go to settings and click ‘Revoke License’.
Next time you use or install Audirvana again you have to type in your license number.

Thank you very much for your advice. Unfortunately, the problem is still the same. I am unable to listen to samples of either rock or classical music.

Best wishes,

This situation was not satisfactory, as I was unable to play most of the music I chose. This lasted several months. I tried Roon, but probably like most here, preferred Audirvana. I cannot switch from Mac to PC. Therefore, I cancelled Tidal and now listen to Qobuz. Thanks to everyone for your suggestions.
