I occasionally get a loud buzzing over the audio from Beam connected with HDMI

Is anybody else experiencing this. It only started happening yesterday and I have had my Beam for about a year.

I have the Beam connected to my Samsung Smart TV using HDMI (ARC) and it happened when I started a YouTube video through the TV YouTube app. There was a loud buzzing noise over the audio. At first I thought it was a TV problem, but I switched to the TV speaker and it was fine. When I switched back to HDMI the problem persisted. I also unplugged the HDMI from the Beam and plugged it back in but the problem persisted. After rebooting the Beam (by removing and reinserting the power cord) the problem went away. However it has happened at least 3 times over the last 24 hours.

It should be noted that if I stream to the beam over airplay while in this state the buzzing doesn’t happen.

Also the Beam is in a surround setup with a Sub and 2 Sonos Ones.

As it just started happening I wondered if it was due to a software update or something.

    I am also having this issue, and would like to add to the above (Samsung Smart TV, Beam + 2 surrounds connected via HDMI). The only thing that has changed in my system is the S2 update so I’m pretty sure its related.

    Watching Channel4 OD in the UK via the TV app - buzzing in right channel occurs only while the main programme is playing but not when the adverts are on. I assume this is due to the audio format of the playout being different for ads. When it first happened using input from a Google Cast it was very loud like a swarm of angry wasps. It was much quieter (though still audible) when it happened using the 4 OD app.

    I did raise a support case but currently having to go through the usual “try a different HDMI cable” , “turn your router off and on” troubleshooting is a bit frustrating. I am not keen on the idea of nailing the TV output to PCM as I enjoy the surround sound (when it works properly).

    Prior to this I was very happy with my Sonos setup.

      Same issue for me. (Samsung Smart TV, Beam + 2 surrounds connected via HDMI) It is a pity. I really hope that Sonos will solve this via a software upgrade. Before the S2, it worked fine.

        When are Sonus going to do something about the S2 update issues? Things are going from bad to worse. I've lost all my speakers from the the app took me over an hour of deleting then re installing the app pulling cables the reconnecting. I'm now experiencing loss of sound from time to time. I have to reseat the hdmi Arc cable to get the sound back. Nearly £700 spent and since the S2 update it's been a nightmare.

        Same problem here.

        LG OLED TV using ARC.

        Switching to PCM makes the buzzing higher pitch and much more unpleasant.

         

        Rebooting the Beam help for sometime but it does reverts.

         

        Happens both on apps and live TV.

          Hi Morten, don't expect much from Sonus. This thread has been going on for months and it seems now we're getting ignored.

          @Vosabhoy

          Do you have a DVD/DVR/Game System that has either and ARC or an Optical port?

          Hi Jean,

          When are Sonus going to admit theres a firmware issue after the S2 update?

          Then I must create a support case on it.

          Here in Denmark we fortunately has 2 years of warranty, and if the problem isn’t solved “within reasonable time” you can demand the purchase to go back.

          Hi Morten, we've the same warranty period in Scotland but this issue wont be resolved by replacing your speakers. Sonus need to fix the firmware issue on the S2 app.

          Even though I would much rather have a working Beam soundbar!

            Hi All,

            I have had the same issue with my Playbar 5.0 surround set up. Started a couple of months ago. 

            The Playbar is optical only so i tried a new cable but that didn't work i have a Samsung TV. I seem to only get the buzzing when the apps are used and then the only way to reset it is to pull the power cable. 

            I email technical support and we have tried assorts of things. Both the software on the TV & the Sonos is up to date (which might be the issue). I have tried removing the rear surrounds (Sonos Ones) and i still get the issue. I then re added them same problem. I tried turning true play off that also didn't work. 

            It doesn't seem to do it as often at the moment and I have sort of given up with the tech support as it seems like they dont know what the issue is. I might email them a link to this thread. 

            If anyone has a fix that would be good to know. 

            Thanks

            Aaron
