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

    my office setup is using 5ghz channel 5825 (165) hmm 

    Why do you think that is a problem @peterbault?

    Also, is your systems showing your HT rears and subs as being in which one of the below? (When you compare your two systems)

    Mode: INFRA (sonosnet)
    Mode: INFRA (satellite)

    Didn’t think it was a problem just interesting it picked such a high channel. Yes my speakers show the same as you

    I just experienced the issue for the first time on my office setup with my LG CX. I checked and the channels did change but they match between the arc and other speakers 

    That is very bad news. Sorry to hear that for sure. 

    However, you did witness a channel change? Are you fairly confident the channel change correlates with the sound drops?

    Also, did you note what channel it moved from and to?

    channel was 5825 (i can’t be sure there wasn’t an issue at this point). after i noticed the issue I checked again and the channel was 5320. same for the Arc and all speakers in that system

    I’m going to go nuclear and completely disable 5ghz on my router and see if it has any affect

    I have passed this onto Sonos Engineering as well and I hope you guys see it too. On the Sonos network review, I see a lot of dropped packages on br0 interface of each of my speakers including Arc, Sub and surrounds. This can be found in sbin/ifconfig section of each speaker. Restarting the device clears the counter and resets it to zero following which it starts building up and then eventually drops out. Can you guys also see a trend here? I have seen that when this count reaches several thousand dropped packets, the sun and surrounds drop out.

      I guess that would be a good test @peterbault 

      The other thing I noted (that when both you and I had a rear/sub drop) was that the channel it moved us to was a DFS channel. That might be nothing, but DFS does mean that each unit needs to have Dynamic Frequency Selection enabled.

        unchecking 5ghz in my orbi settings doesn’t seem to actually disable 5ghz. I’m tired

        This is interesting. Does anyone know if higher bitrate audio streams would build up dropped packets a lot quicker? Stands to reason for me
