Surround System

ARC, sub and surrounds aren’t connecting to the TV audio when I start up.  If I unplug the tv and/or the ARC the system reboots and works but this happens 2 out of every 3 times I start the TV and is a huge annoyance.  The TV and ARC are plugged into the wall behind the wall mounted TV so unplugging them isn’t easy.  I need an easier solution, like the Sonos working every time without intervention. Looking for help from the community as I sit on hold with Sonos support.

My guess is more that the TV needs attention, rather than the Sonos. First, check the TV for updates for its firmware, using the built in menu. Then, reboot the TV by unplugging it from the wall for two minutes. Merely turning it off using the remote isn’t enough. If you want, it would be a good time to power cycle the Sonos, as well. While I recognize this won’t be easy, it may be necessary. You could potentially do the same thing at the circuit breaker, if getting ‘behind’ is too much trouble. 
 

Let us know if Sonos has a different approach.

    A remote power switch can make it easier to power cycle your Sonos and TV but it shouldn’t be needed.

    I use these to power down rooms we aren’t going to be using for weeks or months.

      I’ve done all of these steps and unfortunately the issue remains.

      Get the problem to happen again, within a few minutes submit a diagnostic to Sonos.

      When you have time call Support with he number from the diagnostic and maybe they can see something.

         Which model TV?

        I’m still curious as to what Sonos Support said, when the OP called in, as they said they were doing in their post.

          When support finally answered they couldn’t hear me well so I connected with support via Twitter, believe it or not.  I sent them a fresh diagnostic and they’re saying the Arc is either getting dropped from the network or there’s wireless interference. They have created a ticket and want to work with me over the phone, so I just need to find time during the support hours to call back in.

            Fascinating, thanks.

            Just for reference, there is the wifi interference FAQ. 

            Or, possibly duplicate IP addresses, but I think they’d have mentioned that during your contact. 

            But neither makes any sense to me, since your Arc is hardwired via ARC to your TV…although I suppose an internal reboot might occur. Fortunately,  they have access to the hard data in your diagnostic, something we don’t.

            Still don’t have any definitive answers but I am noticing that when I turn on the tv with the tv remote, as opposed to the Google Chromecast remote which also turns on the tv, I have better luck getting the Sonos to work the first time.  I haven’t had a lot of data points here but it is an observation.  Still doesn’t make sense to me and is quite frustrating.
