Lost surround and sub ( after update ?)

And further, just to possibly help with the worry regarding the problem:

I was in touch with support, and according to the support rep; Sonos is aware of the problem, it has a priority tasking and is being adressed by developers and a fix is expected soon. When asked what “soon” is, the guess is that it is days or 2 weeks max. 

So, there is nothing to do but wait for a new update.

Yeah, it feels like it has been awhile (a few weeks at least) since the last app and/or firmware update, when we’ve had a ton these first five months of the year.  Maybe a lot of focus is on the upcoming releases/announcements, who knows.   

To be honest (and I know this might be contentious) I am more concerned about Sonos acknowledging the problem, confirming they can replicate the problem and that it will be fixed. The time it takes is secondary for me - that does not make it any less frustrating that my surround sound is currently dead, but the fact that the calvary is coming would just reassure me that it will be back at some point! 

Hi everyone, 17 days since I opened this thread, « glad » to see We are a lot in the Same situation…

I thought my issue was fixed after removed and Added again my surrounds and sub to my config, but the problem is happening again.

As I could read, we have to wait for an update which would fix this terribly annoying bug.

cheers 

Just putting my hand up to say I have this issue too. Sonos Arc + Sub + 2x Ones. 

Count me in too.  Arc. Sub 2*play 3s.

I’m looking for someone to try and replicate my troubleshooting success. For context, I upgraded my play bar to an arc a couple weeks ago. All was good for 2 days then I started experiencing the sub/surround dropouts frequently when switching audio codecs or HDMI sources. Power cycling the ARC was the most reliable way to bring everything back temporarily. I never experienced any out of sync issues. I read an HDMI troubleshooting tip that suggested it was important to establish the ARC/eARC HDMI connection from the tv to the soundbar before other connections for stability. With nothing to lose, I gave it a try. My process was as followes and I’ve been stable for around 10 days getting full atmos when available and switching codes frequently without a single dropout. 

1. Physically unplug everything from power and unplug all HDMI cables, both ends (router,tv,Sonos equip, all source devices)
2. When connecting and powering on, do so sequentially and give time to stabilize between steps obviously
3. Power on router
4. Power on TV
5. Plug soundbar into tv via ARC/eARC port
6. Power on soundbar and play content from a variety of audio codecs
7. Power on remaining Sonos equip (subs/surrounds) and play content from a variety of audio codecs
8. Plug in your most used source device (ex. Apple TV) via HDMI and then power on device

That seems to have fixed things for me. I left all eARC/ Atmos/passthrough settings ‘on’ for all devices (ie no settings compromises to mask the issue). I left all other source devices unplugged for several days until I felt the issue was resolved but have plugged in additional devices since and everything is still working. I know others have tried ‘rebuilding’ their systems without success but I’m not sure if anyone has severed all HDMI connections and restarted with the sound bar first. If it hadn’t worked for me I would say this sounds silly but it seems to have worked. I have some ‘highly speculative’ ideas on what might be happening but I’ll wait until I see if anyone else is able to resolve. If not, I’ll just assume I’m lucky and crawl back into my hole 

Interesting. But...How long has it worked for? Not to be “that guy” but I have thought I have fixed the problem about 4-5 times now, only to have it reoccur…

Hey no worries, I did the above procedure on April 30th and I haven’t had a reoccurrence since. 

I’ll give it a try. Unfortunately my tv is mounted in a way that I can’t really unplug HDMI from the TV inputs but I’ll unplug from the devices.
