Confirming that you have re-enabled the extension in Roon Settings and named your Roon Zone correctly?
Depending on your update settings, RoPieee will pull in the latest update. If you manually set the update time to now, and reboot, you can force the upgrade to happen sooner. Be patient, as it takes some time.
I presume that you can play audio out, that the display is the only problem? I assume that you have tried restarting the Roon exension, and your Roon Core, yes? For sure the display will not work if the extension isn’t visible and authorized.
I had this recently and never got it working again properly on the original card. I did a new build on a new card and everything seemed to fire back up OK.
Good to hear – something failed in the original install process for sure. At the beginning I should have suggested sending feedback to Harry, because maybe there is some edge case that can be checked for.
