Connection to Spotify drops. Also, no sound at all from the TV on the Sonos system.

Can you give us more information about your setup like what speakers are you using when Spotify drops, what sound bar are you using, and what model TV do you have?

SamsungTV. Living Room has Playbar, Sub and two Sonos 1.

Have you run TV Setup in the Sonos app? Have you checked to make sure the optical cable has been fully inserted into the Playbar and optical port on the TV? Also be sure the caps have been removed on each end of the optical cable.

Is TV Autoplay enabled under the Playbar’s settings in the Sonos app? Have you set the audio settings on the TV to Optical?

Can’t even get into settings now ☹️

Now in settings.

Lining Room now showing ‘no content’

 Yeah… That’s not right.  There should at least be a volume slider showing a Mute on the left and the last numerical volume level used on the right.

 Can you take a screenshot of your system with the Settings (gear icon) open?

 So when you try to play something on the Living Room it does not play?  The “No Content” is normal.  Only the volume slider for your Living Room looks wrong.  It will say No Content until you start to play something.
