It was working fine and then just stopped working two nights ago. I have an older Samsung smart TV. I have tried changing HDMI cables, turning Anynet on and off, disconnecting the ARC power and HDMI, re-connecting them and nothing seems to work.

I found the solution on another thread here.
Simply unplug the power cord from the TV, let it sit unplugged for a few minutes, plug it back in and voila!

Disconnect the Arc from your TV and unplug both from power for about a minute. Then plug them both back in. Turn on Anynet+ on your TV and redo the TV Setup process in the Sonos app. Don’t reconnect the HDMI cable from the Arc to your TV until the app instructs you to.
