I don’t want Roon Radio to play after an album stops. I deactivated it in all options in Settings>Play Actions. Since the last update it starts nevertheless. That seems to be a software glitch.
The Play Actions only control which options are offered in the Play menu. So removing it there only means that you can‘t start Radio manually from the respective Play menus.
Whether Roon Radio plays automatically when the queue ends is controlled by a switch at the bottom of the play queue. Note that this is a per-zone setting, so you have to turn it off for the queue of each zone separately. Maybe it turned itself back on after the update.
Ahh, that’s it, thank you. I forget where it’s located because I never used it in earlier Roon versions.
