Atmos sound stopped working in Era 300

@posttad  thanks. I am seeing same issues. Gone through the same reset etc. 
 

definitely a Sonos issue. 

Hi,

Thanks for the response. However, a few notes that you should consider:
1) One day before posting my issue here, I was using Era300 through iPhone Apple music app (not Sonos app). Atmos was working fine. Atmos worked well thru Apple music app for the few days after I installed my Era300, but suddenly it failed to work. I am 100% positive about this. Thus, discontinuation of Atmos was caused either by a change in you system or app as my environment remained the same. I have the latest app and firmware installed, also.

2) As you see from numerous posts here, this is not a local issue but appears around the globe. I’m based in Finland, and we'll soon have all continents reporting of the same problem.

3) If your policy is indeed that Atmos will work only through Sonos app, I will return my Era300 (luckily ny retailer allows full refund). Usability of the Sonos app is unfortunately too poor considering e.g. delays and other issues in the UI. Furthermore, I hate companies’ tactics of trying to force their customers to use only their app instead of letting them embrace their favorite choice. Personally, I like to use Sonos app to consume available radio stations not available in Apple music, but your app is far away from be coming my defacto music interface.

Lastly, I note that I tested my Era300 with Sonos app. Unfortunately Atmos works only sporadically. When playing apple music playlist “hits in spatial/Atmos” (sorry not sure what’s the exact English name of the list), sometimes Atmos is on, sometimes not. I fail to troubleshoot rootcauses for this. Then again, troubleshooting is not my responsibily, as a high end product like Sonos should work as promised in your marketing messages. 

Summarizing, I am disappointed. I will give my Era300 still a few days next week, but if the Atmos problems continue, I'm done with the product.

Thanks @Sami71 

 seems there is a growing number of people here experiencing the same issue. Streaming Apple Music through the Sonos app does not produce atmos on specific equipment. 
 

it was working for me a week ago. Now IT is not. 
 

amazon works 100% of the time. 

I'm encountering the same problem as well. It appears that many others are having similar issues.
Dolby Atmos Badge not showing on Era 300 (tried all methods that others had shared) : r/sonos (reddit.com)

 Atmos in Apple Music on Sonos also worked without problems. It disappeared a about week ago. I just turned on Sonos on Ipad in the morning and Atmos on Apple was not there. Unfortunately, Amazon does not work on Sonos in Poland, It is a pity.

I have a similar issue with my Era 300. Won’t play Atmos or Lossless through Apple Music (in Sonos app).

All other speakers in my setup will play Lossless, but as soon as I add the 300 into the mix the Lossless badge disappears.

On its own, the 300 would usually play in Atmos where available, then switch to Lossless if any other speakers were added to the mix.

This started yesterday evening after I factory reset the 300 to fix a connection issue. Was there a firmware update that went live yesterday?

I’m in Ireland and have the exact same problem here. Era 300 stereo pair no longer playing atmos with Apple Music via the Sonos app. This was working yesterday. 
 

Works fine on my Arc with Sub and Era 300’s as surrounds.

Same issue here 

Today I have factory reset all of my sonos speakers to allow me to add apple music (preciously couldn't add apple music, always said something went wrong) and after re-adding Apple Music, I cannot get dolby atmos working on the arc or my era 300s or, when set up, in my surround sound setup.

Dolby Atmos is working fine with Amazon Music Unlimited.

People are having same issue all around the world yet Sonos is saying it isn’t their problem. 
 

Like all the others, I also can get Dolby atmos with Amazon music. 
 

However, like many others, I purchased the pair of ERA 300s with intent to play Dolby atmos music through Apple Music. It that isn’t working, it’s basically a defective product.
