It may be that the TV is not sending IR for some reason, it’s pretty rare for the Sonos to fail. I’d double check that there wasn’t some change in the TV’s set up that turned off the optical out. Easiest perhaps to pull the cable out of the Ray, and see if the TV is sending a red light through the cable. You also want to look at what kind of signal the TV is sending, the most/ highest that the Ray can receive/ prices is Dolby digital. I have seen updates sent to TVs that accidentally mess with settings. 
 

If that fails, I’d  recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Unlikely to be a source issue. I have an audio extractor to get optical audio from an HDMI cable from my computer. I know the computer is still sending sound b/c it plays in the crappy speakers on my pass-through projector still.

So maybe there’s a problem with the extractor then? Possible, except that for my record player, I have an RCA-to-optical converter and that one doesn’t work either. Both worked fine yesterday, and it’s improbable that both pieces of independent hardware failed simultaneously. 

I’ll try the system diagnostic & call Sonos.

I can’t imagine the optical input issue relates in any way to the Amazon music issue. No idea in which way that could be…

I also recommend first to check optical output and input on hardware side. If available try a different opto cable. Sometimes moving the cable at the plug just a little bit can help and would be a proof of damaged cable or optical port. 
To check Ray for a general issue with digital input you could try to connect any other source device with an optical out e. g. a dvd or bd player. 
 

Edit: @Rebelfish …sorry we were writing our posts at the same time. 

@Rebelfish 

Did you run a test with a different cable? These optical ones are very sensitive.

Apparently I just needed to go into the TV Setup in the app and click through things, and that refreshed the Ray so it was looking for optical input again. Not sure why, but that did the trick. 

@Rebelfish

Congrats you got that sorted…

And btw Sonos status page shows an Amazon music issue..

Let’s hope that also will be fixed soon.

I’d double check what kind of signal your computer is sending over to the converter device. If it’s anything other than Dolby digital, it can’t be sent across optical. It may require looking at both the computer’s settings, as well as the app you’re using. 

Thanks -- that’s a useful page to bookmark, before diving into issues on the local end one things stop working. 

@Rebelfish 

Yes, it definitely is… and on top if you are browsing any Sonos site on the net including the community there is a red info pop up that informs you about the latest ongoing issue if there still is one.
