Not a problem, per se, but I’m wondering if there is a way to have Roon shut down your computer at the end of the “Now Playing” playlist.
Thanks!
Moved your question to future request.
Roon has no OS controls but I am sure an api call can be cron if you use Linux and call on a shutdown command. Just ideas 
The OS may be able to approximate this action on its own if you set the power settings accordingly. Once Roon stops playing, my computer goes to sleep in an hour. Also works with Roon Bridge.
