Have you tried a factory reset of your TV? Be sure to write down any video settings you have changed so you can reset them.

After factory reset, be sure you have the latest firmware on your TV. Then turn on Simplink and enable any HDMI ARC settings. Then try to setup your Arc again with only the Arc connected and nothing else.

Do you have Simplink (CEC) turned on in your TV settings?

Have you tried unplugging your TV and Arc from power for about a minute and trying TV Setup again in the Sonos app?
