Hi 

I don’t know if my issue is related to the 14.6 update but I noticed today that I had no sound from my surround (play 3) and my sub (Gen 2), only the Arc is working They are still present in the app under the my System view but now sound which every sources

When I reboot each of them, the sound comes back temporary, but when I switch to another source or audio format, thé Sound disappears again. Tried several times, same behavior

Thanks for your help

    One quick question that may be unrelated:

    During all of this I have noticed that I cannot disable Wi-Fi on the Arc or it will cause immediate loss of surrounds and sub. The arc is wired, the surrounds and sub are not. I thought the Arc had its own networking to the surrounds / sub not relying on Wi-Fi.

    So should I be able to turn off Wi-Fi on the Arc and still have sound from the non-wired rears and sub? Or am I experiencing expected behavior?

    thx!

    You need to have Wi-Fi turned on in the ARC so it can connect to the Surrounds.  I have my Wi-Fi disabled on the ARC but that is because every speaker is wired with Ethernet.

    @foxisif you deactivate the Wifi of the arc even while being wired, you lose the Sub and the surrounds!

    By the way, although my testing led me to experiment with a fully wired system, I can say it does sound awesome! Not because it makes the sound better, but the speakers fire the exact time they should which creates a very nice and coherent sound stage. 

    Pity I am going to have to unwire all this when the issue gets fixed!

    I’m fully up to date with the app and Sonos firmware and I’ve just lost the sub and surrounds on my Arc. Happened when I switched from PC source (HDMI) back to Freeview on the TVs internal tuner.

      always a change of source at the root of the problem...

        I keep going around in circles. Yours was one case where tv internal apps appeared to be involved but Windows uses Dolby Mat. Do you have any sense for whether using your PC could be triggering the instability? Have you tried disconnecting/reconnecting everything HDMI wise and power cycling everything? Is it possible to regain and maintain stability that way if you don’t use the PC at all?

        I’ve experienced this issue many times before tonight, always the same symptoms: the surrounds disconnect (after changing sources), then require reconnecting using the app. The whole time, the Sonos app never registers anything as being wrong. 
         

        Tonight, something different occurred: after changing sources (LG Plex app —> Apple TV) the surrounds disconnected as usual, but this time the Sonos app said my Arc was offline, with the spanner icon (with LS?RS? displayed as well). 
         

        This time, it needed a complete power cycle on all three devices for it to work properly again. Thanks 14.8!

        I’ve not pinpointed if it only happens when switching from PC to TV but I’m pretty certain it also happens when switching from TV to one of the internal apps.

         

        Ive just switched from TV to PC and back again to see what happens and I’ve now got the issue where the surrounds and sub are out of sync.

        And a few minutes later, it now sounds like it’s sorted itself out without touching anything.

          when you say “switch to TV” what exactly do you mean?
