Connect - no sound

I have a system with one connect and three connect:amps, no sound plays from the connect. 
 

I have them grouped, with audio coming via line-in on one of the units. Which unit the line in is hooked up to (connect or one of the connect:Amps) has no effect on the problem. The connect line out is hooked up to a receiver. I’ve hooked another source up to the receiver’s line in and it plays fine. 
 

If I have the line in hooked up to the connect, all units grouped, I get sound out of the connect:amps but nothing seems to be coming from the connect line out. The Sonos app shows them all playing and volume is turned up.  Any ideas what I’m doing wrong with this setup?


Thanks!!

Just tried the factory reset and that hasn’t changed anything. I don’t have a toslink cable available but I’ll pick one up and try the digital out. 

Ah sorry to hear that. It was worth a try at least. If the connected Receiver does have a digital input (coax, or toslink) that seems to be the next step, I guess.

As a temporary measure, try using one of the RCA analog cables to connect the digital coax out to a suitable input on the receiver. So long as it’s not very long it should work, at least as an experiment. 

It works!!! So it seems the analog out has failed?

Now I have a new problem - the audio isn’t synced with the amp outputs. I’ve tried playing with the audio delay but I can’t get them to line up. With all delay settings the same, the speakers connected to the Sonos amps are ahead of the the connect optical output.

The receiver is doing audio processing, incurring a delay. See if it can be disabled, via a ‘direct mode’ or some such.

BTW I’d recommend moving to a proper digital coax cable if you’re going to stick with using that Connect output.

There’s an improvement but it’s still not good enough for listening... Maybe getting different amps to play together was a fool’s errand from the start 🤣

Thanks to everyone for your help here, it wouldn’t have occurred to me to check that the line out had failed!
