Lost surround and sub ( after update ?)

I am with you Peter. I think I have exhausted the extent of my knowledge on this one. I need to keep chasing my open ticket (been 2.5 weeks now, no response) and need to keep supplying further info. But, quite literally, I have nothing left that I can test. (Apart from a few tidying up items). 

My entire system, a sub, arc, sonance architectural on an amp 2, two ones, a move, and a connect have all had intermittent drops and sync issues between all of them. The ones and move are isolated in rooms, so not a big issue but have come up as issues in the app. The consistent problems are sub dropping, and architectural speakers dropping regularly from the arc grouping. Today I found out the record player (through the connect) was also experiencing the same issue. I haven’t had any issues whatsoever for almost 6 years and since the new update have made at least 7 calls to support, submitted several diagnostics, with no solid solution for 4 weeks now. At my breaking point of ditching the whole system. 

Humble request to @Sonos to diagnose and roll out a beta release to only the affected users, this is the only thing that makes sense. Roll us back to pre 14.6 and allow us to monitor if we still get the same issue. This then gives Sonos engineering a chance to diagnose what’s changed post 14.6 that is significantly causing this dropout issue. My 8 year old Harman Kardon SB26 performs better than this and has always played music no matter what at the very least. @Corry P and @Sonos - my HT system is going end of warranty soon in Aus, please update if you are able to rollout a fix or assist to return the entire system. It’s an expensive system and we have all been very patient, co-operative at the same time and I think everyone deserves to have a working system at the very least.

Have you spoken direct with Sonos Support and had your diagnostic reports checked? The Staff are suggesting you submit your diagnostic report within 10 minutes of seeing the issue and note the reference and then contact Staff via the link provided below, as they are apparently looking at each incident on a case-by-case basis…

Friday evening I installed voice assistant on the Arc and the whole weekend it all works fine.

Switching between Ziggo next tv box and tv apps is not a problem anymore.

Strange butt it works for now.

My Arc dropped last night while I was watching Spiderman No Way Home, (multichannel pcm 7.1) I paused it and went back and no audio, even the lights on the front where not flashing from volume presses, so it had completely dropped.

I was watching via apple tv 4k gen 2 box.

I switched source to live tv and back again and the ARC started responding again, can tell as you see the tree light turn on for a few seconds.

Hi all,

Firstly, thank you all so much for all the testing and debugging you’ve been going through. Hopefully it’s going to give the Sonos engineers a solid foundation to (eventually) rectify this awful problem. 
 

I’ve just got home after 2 weeks vacation to find this issue is still constantly occurring on my system. Please can somebody give me a quick rundown on the Voice Assistant / power-cycle method of improving things? Does it legitimately help the problem do you think?

Thank you!

1. From my current June 2022, hands on experience comparing Sonos 5.1.2 side by side with the HT-A9, seems Sony has fixed this issue. However, Sony also includes an RF Channel feature in the menu that can be used to minimize interference or select the best/stronger channel for transmission if you do encounter interference from other wireless devices in close proximity.

2. I have a very powerful Asus ZenWifi mesh system running in my environment. No Sonos dropouts.  

Since the svc release the only dropouts I have had have been with my pair of 5's and sub gen2 

Left channel dropped followed by the right a remove and readding them fixes it but then I have to redo truplay which is annoying 

My surrounds have been stable for over 3 weeks all of my speakers have svc installed which makes me lean towards a software issue as the 5’s are unable to install svc and they are the only speakers still having dropout issues 

Hopefully when 15.x release drops we can put 14.6 in the rear view mirror 

My two cents...

Well, If voice control is the fix, they need to look at what in the coding would affect the basic ARC vs the SL ARC. I have the SL and voice isn't an option for me.
