Home Theater system

True I could have, but then to say if I would have ever been able to interact a bunch of friendly and great people such as you. Thank you for all your contributions!

If you go to Settings-(HT room name)-Surround Audio-Music Playback is it set to Full.  If not Set it to Full rather than Ambient.  Now, from within the Sonos app, play a stereo track and see if it plays from both rear speakers.

The OP has already been informed by Sonos Tech Support that the speaker in question is not region specific to the OP’s system. Therefore it won’t connect. See original comment about five posts up. 😊

Thanks.  Somehow I missed that.  I think I sent a reply not noticing there were two pages.  
 

Why are there different regions assigned to Sonos speakers.  Does it have to do with what services are available in what regions?

Sonos hasn't said much about regions that I have found, usually just noting there were the problem.

Maybe not services, possibly radio operation and licensing issues?

The only thing I can imagine (since there is a cost in maintaining two production lines) is a difference in WiFi channels that it can/may connect to. 

That is a possibility. I also think it may have deeper implications such as the pirating of containers at port of departure and/or entry.  Not necessarily the entire container but specific products/components inside. That thwarts the black market that may try shipping/diverting stolen merchandise to other destinations than originally intended. 

Interesting conjecture. Certainly not impossible, but gosh, I hope crime isn’t that bad….

You’d be very surprised…so hold on to your seat…

Cargo theft has always (well since the 1960s in my direct experience) learned early on that you shipped your household goods as cargo but anything with resale value got sent by the military post office.

Now with cellphones to document everything's location within a container it is even easier for the thieves to target just what they want. That is actually a good thing as it reduces collateral damage.

Commercial theft is even more lucrative now, with modern tools for the crooks.

Still leaning to the radio being the issue, looking at a rules and frequencies matrix you can't easily build a single product to fit all regions. You can build a single physical product that has hard controls (locked firmware) if you can prove to the regulators that the lock will prevent use outside the allowed range of frequencies and rules. That of course opens a can of worms if you can reload the operating system with one of your choosing and reconfigure the radio to use any internally available options regardless of local rules.
