I wish to use a Sonos Ray simply as an external speaker for a TV via the optical input.  I have only a public network available and can connect my windows 10 PC to the Sonos device as it is listed in the available network devices.  My Norton smart firewall is disabled

The Sonos app cannot connect to the Ray and I get the “Try Again” message.

Suggestions are welcome and have considered that this unit is not appropriate for this situation.  It must tolerate occasional loss of power without any computer intervention to recover.

I did change the TV to send audio to the optical output but the Sonos does not decode it in the absence of the setup process.

Thank you,

Mike
