Sonos beam gen 2 sound connectivity issues with Samsung QE55Q80

i am sorry that it’s not work for you. for me it’s works every time i turn on my tv.

i just want to point out that on my apple tv i put a HDMI CEC blocker that help with my solution.

The issue with the disconnection is happening even if I don't have any other device plugged to the other HDMI ports. So, even with the CEC switched off on my nvidia shield doesn't change anything appart of my TV remote doesn't control the media player…

Bonjour

j’ai le même probléme et étant donné que c’est lié à la mise à jour en 15.9, savez vous si il est possible de redescendre en 15.7 ?

Merci

I don't know how and even is it posible. With the new upgrades they implementing changes in their services which I believe is the thing what stop them issue tool for downgrade... 

Sonos does not do roll backs to older software versions.

So far I don't have luck to chat with real person in live chat session. Ony with chat bot and evry time i am getting to dead end. West of time. 

Probably i need to give the technical support a call but i really don't heve time in the working hours. 

Bonjour à tous,

j’ai enfin réussi à résoudre mon probléme aprés 2 appels à Sonos et 1 appel à SamsungL

Avec Sonos nous avons retiré tous ce qui étaient branché à la TV sauf la Beam

Puis j’ai retiré également les mises à jours automatique (sur l’iphone) Sonos

Puis j’ai appelé Samsung et on a fait un reset d’Usine - attention pas celui que vous pouvez faire seul - celui fait par le technicien Samsung 

Et Depuis je ne perd plus la connection E arc toutes les nuits 

Par ailleurs il faut noter que ma tv est passé sous une version 1602 entre temps !

Bref vous l’aurez compris je ne sais pas si c’est l’arrêt de la mise à jour ou le reset de la tv qui a résolu le pb.

Bon courage à tous

Hello everyone,

I finally managed to resolve my problem after 2 calls to Sonos and 1 call to SamsungL

With Sonos we removed everything that was connected to the TV except the Beam

Then I also removed the automatic updates (on the iPhone) Sonos

Then I called Samsung and we did a factory reset - be careful not the one you can do alone - the one done by the Samsung technician

And since then I no longer lose the E arc connection every night

Furthermore, it should be noted that my TV has been upgraded to version 1602 in the meantime!

In short, you will have understood, I don't know if it was stopping the update or resetting the TV that solved the problem.

Good luck to all

I tried factory reset through service menu. Not the standard reset from the TV settings. 

Through the process of setting the TV for first time you are asked to connect all hdmi devices. All is recognised, sonos beam gen 2 also. 

On the next day in the morning again the connection is lost :(

I keep my sonos auto updates off from long time and checking manually but I can't see how that can help with the problem. 

My Samsung TV also is on 1602 firmware. 

So, no luck again. 

Still waiting for update from Sonos side. 

I am very disappointed that Sonos failing to solve that that long time. 

I am regretting buying their products and will not recommend them if i am asked. 

Bonjour ves, j’avais essayé une réinitialisation via le menu et cela n’avait rien donné, donc je t’encourage à faire une réinitialisation avec un technicien de Samsumg, je n’y croyais pas mais pour moi cela a fonctionné
