Hey @Marcin-grzes,

Welcome to the Sonos Community and thank you for your post!

Sorry to hear you are getting dropouts on your left Era 300 in bluetooth stereo set-up. Great stuff, checking the software is up-to-date!

I have a few more ideas to narrow down the issue:

Have a look at this guide especially about reducing interference.

Do you experience similar drop outs if you target the players over Wifi?

Does playback from another music source via bluetooth, like your phone, also cause this issue?

Does playback on the Eras via bluetooth as single players produce the same symptom?

And lastly, when you swap the players around in the stereo pair (you’d need to reconfigure the stereo pair in the app), does the drop out disappear, move with the former left speaker or stay on the new left speaker?

Let us know how you got on!

Hi @Gabriel Z!

Thank you very much for the reply

I tried all the things in the order you wrote and when all hope was lost, the left-right swap and reconfiguring the stereo pair did the trick, no drop outs yet!

I think this issue appeared after some time, I was using this setup for a couple of months already and noticed it only recently, but so far so good after a few hours of testing now, so I think it is solved :)

Will let you know if it reappears (hope not tho!)

Thank you again!  

For anyone that will experience the same, I got another solution. So after you pair them as stereo, you have to choose which era 300 to connect with for example the tv. First I connected it to the era 300 which is actually close to a router, issue happened all the time. Than I deleted the Bluetooth device from my tv and pressed the Bluetooth pairing button on the other speaker so the tv could see that one as the main, and problem solved. You don’t need to swap the speakers, that’s not needed in my opinion since they have the same hardware.
