My Sonos arc has always worked fine and volume controlled by all remotes. I paused a show for a moment and when I returned the sonos arc was off and I am unable to even turn it on (get a light of any sort) again.

It’s also possible the TV shut down CEC. As a precaution, it might be worth both checking the TV for updates, then unplugging it from the wall for 5 minutes, to force a reload of the OS.
