15.8 update is a nightmare

I always thought that was the security platform for their mobile devices🤔… a list of Samsung products that use knox are shown here:

It would make sense (perhaps) if Samsung do use some kind of TV security that sets them apart from other brands of TV. It would explain why most other brands are not affected by the recent updates. Anyhow I’m fairly sure that Sonos/Samsung will resolve the issue at some point, going forward, and hopefully that will hapoen sooner, rather than later, for those customers who have encountered these issues.

edit: Oh and I would personally wait, rather than disable any security settings, as that may invalidate any Samsung warranty/support etc.

Just use the Optical-to-HDMI adapter for the time being - very little is lost between Atmos and Dolby Digital 5.1 surround sound.

OK so first of all it’s good to see I am not the only one experiencing this issue.

This is most definitely a SONOS issue as it only stopped working for me roughly a month ago, around the same time the OP posted… and there had been NO changes in my setup or any Samsung firmware updates that I can see.

I have been constantly in contact with SONOS support for the whole month on and off about this, with a vacation away in between. For the most part, they have been helpful and keep giving me troubleshooting tasks to try. I have done so many but the issue still persists. It’s normally when the TV has been on standby for many hours that the problem repeats itself when the TV is turned on. I have to manually reset the power to the beam. We have tried such things as leaving only the beam connected via HDMI, power cycling both the beam and the TV and even switching my beam gen 2 with another beam gen 2 in a different room (ironically connected to an older Samsung TV and has NO issues whatsoever). Regardless of all of these”tasks”, the fault remains to this day.. leaving me annoyed beyond belief, especially when paying upwards of £3000 for my home theatre kit (including TV and subsequent SONOS components).

One person I spoke to in support did actually confirm they were aware of this “issue” and that there should be a fix coming for it. I assumed he meant in the latest firmware update that came through last week but alas this has not fixed the issue for me. I still hope that a proper fix is on the way. 

My only temporary solution that I have been thinking of doing, especially if this becomes a long term issue, is to have the beam plugged in via smart plug. I could then setup a shortcut on iOS to trigger the beam to turn off, wait a few seconds and then turn on again… which will then in turn mean it will reconnect with the TV. It’s really not the best solution by any means but it will stop this annoying issue and the beauty of shortcuts is it can all be automated to work with when the TV powers on too. I will try and create this shortcut on my next set of days off if anybody is interested in a similar function but it should be easy to create.

I just hope and pray that there IS indeed a bug fix for this coming. I used to love how amazing my home theatre kit worked but currently it just feels tainted by all of this. I just want everything to work as it should, too much to ask? 

@DIZZYDJC,

It appears a number of users in the community have been informed by Sonos Support Staff that the matter was being looked into, so I’m guessing that’s the case - it perhaps a case that once it’s fixed, the engineers will go onto test that the fix works in conjunction with Samsung etc. meanwhile you could as a temporary measure use the Optical to HDMI adapter that came with your Beam - you will lose Atmos audio but still receive 5.1 surround sound - but that’s perhaps better than power-cycling your devices, plus it’s only temporary until an update is released to hopefully fix the issue. I would also keep an eye out for Samsung updates too, just in case they change anything at their end to accommodate.

Hope it gets sorted for you soon. 👍

Would be the answer but I didn’t keep my optical adapter lol

Smart Plug idea will work for me for now and hopefully will all get fixed soon too. 

I installed update almost a week ago and it seems issue is close to resolved in my current TV setup with CEC-Less adapter on a 2nd device.

Only 3 out of approx. 50 times of TV power ups - Beam was not connected, definitely they improved Beam connection. Plus I think it seems they added some kind of watchdog reset with firmware 15.9 as after 1 minute or 2 minutes TV picked up Beam (kind of soft power cycle) when it was initially not connected.

I will remove CEC-Less adapter from my 2nd device connected to S95B TV from today on and I will see if it still works as supposed to on 15.9. I will post my results after few days.

Also I set firmware updates to manual, as in case new firmware breaks something, you can hold off with updating until it is safe to do so. It's bad to pay 2 or 3k for the speakers and struggle to use them and go thru all that hassle. Hopefully things are getting better.

I’ve found a workaround for myself until Sonos and Samsung fix the issue.

My disconnect of the Sonos Beam Gen2 to my S95 was caused by a CEC issue from other external devices turning on the Samsung via CEC over HDMI. This establishing of the new CEC handshake was breaking the one between Sonos and S95.
 

I have an AppleTv connected to the S95 via HDMI and using CEC. Using the Apple TV remote to turn on the Samsung TV and wake the AppleTv after being in standby was causing the S95 and Sonos to lose its CEC map, hence defaulting to TV speaker.

To resolve this issue. I’ve set my external devices (appletv) to never go to sleep, and I only use the Samsung remote to switch the S95 on and off. I can still use the AppleTv Remote to change the Sonos volume.

Because the CEC connection for external devices always stays alive due to those devices not going to sleep, and because I am not switching on the tv via CEC no more CEC handshake drops for the Sonos.

update: i found a great solution that work for me every time i turn on my samsung tv.

before i turn the tv on i open the sonos app and move the volume up and down this wakes the beam 2 from a sleep mode and after that i turn on my tv and every time the beam 2 connect to my tv with no problem at all. this is much more convenient solution compared to unplug the power cable and plug it back every time i turn my tv on.

After removing CEC-Less adapter, the issue is still present. Beam 2 is not detected after some time.

When this happens TV won't switch off. It's switching off screen for 0.1 sec and then display is back on.

Power cycle needed to fix. I installed smart plug for now, to do power reset.

Will try the trick with volume up and down to before switching on the TV.

Anyway this is only workaround, we should not deal with that kind of issues. Sonos please fix this.

It should be allowed also to downgrade firmware to last stable version, but there is no option to do this.

from the beginning i say why sonos don’t let us to downgrade the frimware this will fix all the problem.

if i can go back to 15.7 i stay with this frimware for ever.
