Arc stops working with TV , was working fine

My Sonos Arc has been working fine the last weeks but a few days ago the audio from TV stopped working? Seems like the Audio Return Channel function just stopped?

I still see the wallpaper from Sonos when I choose the HDMI - ARC source on the TV, but no audio.

 I have tried all the regular stuff like unplugging the HDMI, cutting power and fiddled around in the TV settings.

TV: LG 65UH7700

Sonos Arc+sub

nothing else attached to the TV

This seems to be a similar issue that many people have, but I have found no definitive fix. Any ideas?

    Hi @kdto - if the Arc isn’t getting a signal from either the HDMI-ARC or Optical ports, then I’d recommend reaching out to our Support Team via live chat or phone call.

    They’ll be able to take a closer look at what’s happening and go through some live troubleshooting with you :)

    Try switching to an optical connection and see if that works.

    What is the source device, has that changed recently (eg firmware update)?

    My arc just stopped sending audio from my Sony tv. It has been working fine for several months. I tried unplugging it from power and hdmi but no luck. It still works with Alexa and through Amazon music in the Sonos app. I checked and the tv software is up to date. Does anyone have an idea of what I can do to solve this issue. 
     

    Thanks

      @DmSchofield Try unplugging the Arc, TV, and HDMI cable and redoing the setup process.

      Same here, working for months and just stopped. There was a software update for my Sony but not at the time it stopped working (was weeks after). I am in the AV industry for over 25 years so I am pretty sure this isn’t user error - have done detailed troubleshooting and setup everything fresh multiple times.

        Same issue… I use Sonos at two homes on different accounts- one with Samsung QLED and google wifi, the other with LG OLED and netgear router. We have used Sonos for several years, 10 speakers in total with no issues. Something about the combination of S2 and Arc soundbars have made both systems extremely unstable. There are constant dropped audio streams, disconnects from the TV or the network, loss of surrounds from the system, etc. 

         

        Tech support by phone has been unable to help. Forums always blame user error or router / network config. It’s extremely frustrating and disappointing. Please fix it. The ability of these speakers to play audio is not a feature- it is the core function and needs to be reliable.

          Having this same issue suddenly. Everything was working fine (LG OLED and Arc) but started to experience sound issues when changing input sources on the TV over the last week; and now no sound via Arc today.  Unplugging, turning off/on TV worked previously but no longer. Have tried all the troubleshooting - unplugging, resetting TV, resetting Arc, checked all settings on TV. I tried plugging the Arc into the optical port with adapter and still nothing.  I swapped the Arc out for my old Playbar connected to the TV via optical - it worked fine.  I tried changing HDMI cables to the Arc, no luck.  Seems like the Arc input is just not functioning?  It cannot detect a signal any longer in TV Setup in the app.  Has anyone come across another solution? Thanks!

            I have the same issue. Sonos arc connected to my Samsung Q80t suddenly stopped working. Tried all reasonable troubleshooting steps (switching on and off all devices, disconnecting and reconnecting etc.) but Sonos arc can't get any signal from the TV from eARC port. My Sonos arc is less than a year old and try to return it and never look towards sonos product..so frustating.

            Another reasonable step would be to ask Sonos for help. Have you done that?
