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 having exactly the same issue with an LG TV, only appears to happen with UK HDchannels, it seems the only way to fix this is to disconnect the power lead from the Beam and then reconnect it all appears to be good then. I would be interested to know what the permanent fix will be.

    Fixed by changing digital out from tv to PCM instead of auto

      I have exactly the same issue. It is the same low frequency buzzing noise coming from the playbar. This is connected to Samsung tv via optical cable. Happened to both while watching  tv and youtube. I will try to unplug everything and put it back as above to see if it works. 

      Very weird this is just happened today.

      That just switches the TV audio output to stereo, rather than Dolby Digital surround sound (when available).

        I have the same problems with buzzing. Started couple days ago. Sonos Beam with 2 1’s surround. Have had the system about 2 years. Starting to see quite a few Beam owners reporting the same problem so I hope Sonos does not waste our time with stupid basic troubleshooting like cable..etc..

        For now I just listen to sound through the Samsung TV. Guess they will figure it out at some point. I miss it but not a show stopper…..

        Same exact issue. Samsung Qled with HDMI ARC connection on a Beam with Sonos 2 and two Ones as surrounds. All updated and working fine for weeks since I’ve had the Beam as my surround home cinema setup. Since today it starts buzzing in YouTube app on the tv from the right channel after several hours or sometimes even within 20 mins of a powercycle of the Beam. If I use tv audio it’s perfect so the tv speakers and data is ok. When I add the kitchen One to the Beam group the buzzing is also added to the kitchen sound so it’s not the hardware of the Beam. It’s definitely a software glitch as a reboot always fixes it. 
         

        looks to me like the new Sonos 12 software is not playing nicely with the tv audio stream. 
         

        As a long time enthusiastic Sonos owner I do hope this will be fixed asap. This is a real pain in the backside.

          Totally agree with Konimex that its a software glitch introduced with the 2.0 release. I will be patient and just wait for SONOS to fix the software with a update. No point in communicating with the support personnel and waste my time.

            The Playbar once had a genuine bug caused by an update.  The main thread about the problem hit 100 pages in a few days, and there were dozens of other threads as well.  Far more likely is there is something going on locally, and you should submit a diagnostic and post the reference # here to get it looked at.

            Nope - Other threads with the same problem as well. Its not local. Some will have the problem and not know what to do, others have probably not updated yet and then you have the totally clueless. Worked great for 2 years and started acting up with the 2.0 update. I am not going to deal with a 1st level support person that just looks at canned basic questions on a screen.
