All morning I have had this same issue. When hitting play on various songs, Roon displays the sliding blue back and forth bar I assume as it is retrieving the song from the library. This happens when selecting various songs, the Radio works fine. I have restarted roon, I have restarted my MacBook. It is not the DAC/amp connection as I know what to watch for. After a reboot one time it did work one time, I paused for 5 minutes and tried to play the same song and it did not work (the same sliding blue back and forth bar). The bar of course is the progress bar depicting how many seconds into the song you are listening to.
Core is on MacBook Pro 10.14.6
Roon Latest 1.7 505
WiFi connection is very good
USB connected to Focal Arche DAC
Playing from me Core but the remote via. iPhone has the same issue.
Is this some issues with your servers?
Thank you in advance.
