Hi team 

I'm having trouble with my new Era 300. Unsure if it's user error, generation of products not getting along, or an issue with the app.

I have a turntable connected to the Era 300 via line in. It plays audio from the Era 300 without issue.

I have a separate speakers, in a different room, consisting of a Beam (gen 1) and 2 x symfonisks as surround ('living room') 

In the app, I am then attempting to share the sound with the living room speakers, by ticking the living room in the grouping option and selecting 'apply'. 

When I do this, the sound stops from the era 300 and is not shared with the living room.

When I reopen the grouping option, the living room is Un-selected. 

This seems to repeat - as if the living room is rejecting the audio from the era 300.

Really is a bummer, as I only bought the era 300 so I could share the turntable audio across rooms. 

Any ideas?

Seems odd, it definitely shouldn’t be happening like that. 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.


Try resetting both the Era 300 and the Beam. This can resolve temporary glitches. To reset, unplug the device from power for 30 seconds, then plug it back in.


Thanks for the replies. 

Spent an hour on the phone with the helpful tech support team.

We tried several ways to get it working but to no avail. 

Significant bugs in the app resulting in grouping functions not working, as well as source information dropping in and out from the homepage.

Ultimately he was unable to resolve the issue, logged it with the dev team and we said goodbye. 

I will also be saying goodbye to the Era 300 and sending it back for a refund.

No more sonos products for me.
