I use roon with tidal. I have tidal set to max setting. All my roon songs play at 44.1/16 even if the tidal output is high res. I’m not getting what I paid for.
You may want to ensure that you have “Max” selected under Tidal. Go to Settings/Services/Tidal and hit Edit.
Ensure the drop box shows “Max”.
Restart Roon and check that the files now play at higher rate. If they do not go back into the Edit Screen and then Log Out of Tidal. Log back in to Tidal and then restart again.
This normally works to get you to the Higher Resolutions.
