Roon proclaims all tracks in this album are corrupt

Yet they play in Sooloos.

I have examined them with STAMP ID3 tag editor and Mps3tag to no avail. Anyone suggest what is going on?

I might try converting them from FLAC to WAV to see if that helps.

The files might play, but something internal within them does not conform to the FLAC standard.

No WAV does not support tags [well], I’d recommend transcoding the files from FLAC to FLAC (dBpoweramp and many others can do this) which normally sorts out the problem.

Thanks Carl. Been busy with other tasks so haven’t done anything more yet but will follow your suggestion tomorrow and will report back.
NEXT MORNING:
Worked like a charm - all done.
