You’re playing a DoP file (i.e. DSD encapsulated in PCM). Roon supports DoP output but does not support DoP file. Contrary to the thread title, this is not a supported file type in Roon.
You can use Lumin app to play this DoP file, but Roon won’t work.
If you really want to use Roon to play this, you will have to convert the DoP file to DSF.
Instructions for using VinylStudio to convert DoP file to DSF:
In VinylStudio, import the DoP files, make sure that they’re detected as DSD. In the tab for Save Tracks, click More (do not click the Save Tracks button ), choose Convert Recording Format and DSF. After the conversion is done, close VinylStudio and launch Mp3Tag to copy the tags from the DoP files to the newly generated DSF files.
When you try to play the converted files, turn down the volume in case there is any error or setting issue.
