Don’t forget if you’re still having issues with your Soundbar and a Samsung TV dropping out, that Sonos Staff in this thread have said to submit a Sonos system diagnostic report from within the Sonos App, note it’s reference and then contact/chat with Sonos Support Staff via this LINK, although it’s probably  best to perhaps do that after the holiday/weekend.

I don't know what's going on honestly. For the last couple of days i haven't had any issues and TV stay linked to the Sonos beam gen 2. 

I don't know what I have done but for now all is good. 

I am mad. The issue still exists. I spoke couple of times with Sonos, sent multiple time diagnostics and no help at all. They saying the reported previously issue was fixed with the latest firmware but it wasn't for me. I contacted Samsung couple of times and they were absolutely useless. I am really disappointed. 

It is such a shame for both companies... 

i don’t know why you blame samsung the issue is only sonos bad 15.8 frimware.

i am the first one that identified this issue and announced sonos about the issue. at first they denied that the problem is on their side but after they see that a lot of customers have the same issue they understand that the issue is a frimware problem.

until now they did not find a solution to the problem. and what remains to be done is to wait for a frimware update that fix this issue.

according to past experience with same issue with sonos it’s take time until they fix a issue in the sonos system.

I have red customer report where samsung engineer through the service menu manage to solve the problem somehow. I was not very happy that after a few calls they just were going to obviously some written troubleshooting instead of going through some diagnostics. However i am not engineer and can't teach them how to proceed.

Sonos collected my diagnostic reports and absolutely denied problem to be from their side. After knowing that they actually recieved diagnostic i belive them more than Samsung. Now I'm not sure who to believe.

Sonos knew about the issue and recently realised the second firmware update since the problem was reported. After second sonos attempt i thout that issue really was solved and only i am exemption because sonos didn't tell me that more people like me still reporting. 

You have to separate two issues the first issue that the sonos beam 2 stop in the middle to work this issue fix by sonos.

the second issue that is the bigger issue that is the issue that all we complain about it is the issue that when you turn on the tv and the beam not connecting to the tv. and for this issue sonos until now not come with a fix.
