After updating to S2, my Beam started making a buzzing sound when playing from the tv.

If I disconnect the cable from the tv hdmi ARC port , the sound keeps buzzing and only Stops. when I disconnect the cable from the beam  
the buzzing only comes from the beam and not from the surrounds  

im using the included original cable 

when playing music from Spotify it plays normally. 
 

any idea what might be causing this?

 

thanks,

    Thanks Mark but I seriously doubt they can help me with this, as it’s exactly the same problem as everybody else here.

     

    Problem persisted tonight so I made two diagnostics before restarting the Beam

     

    TV set on “Auto”:

    305109054

     

    TV on PCM:

    457552263

     

    As said the noise is on both settings, but it higher pitch in PCM.

    Unpluging and repluging the HDMI cable changes nothing, only rebooting the Sonos does.

     

    Btw: is there a way to remotely reboot a Sonos device? I’m tired of having to unplug and replug 😏

    😕

    Just tried to switch to optical using the supplied adapter, same problem.

     

    Did not try rebooting the Beam, my wife’s patience was running out 🤬

      Same problem with the buzzing issue on the Sonos Beam.  I have done All the troubleshooting techniques. (Plenty of resets, tried different HDMI cables, tried optical.)  It always keeps coming back.   Sonos support diagnostics show nothing wrong, even though it’s clearly there.  Very frustrating

      I have the same issue - I’ll try and do the factory reset to see if it works.

       

      A couple of things I did not see mentioned here:

      1. The buzzing sounds only when there’s sound coming from the TV
      2. My TV has 2 output options: “PCM” and “Auto” (i.e. what the source format is). I normally have it set to Auto since PCM means stereo sound, and I get the buzzing - even if the source is PCM!
      3. If I set my TV to output PCM and not the source format, it stops buzzing completely, but as soon as I return to Auto, it starts buzzing again.
      4. After power cycling the Beam, it seemed to have worked for a while.

      I have a Samsung 49" Q6F and just started having this issue after the S2 update as well. Did a reset and it started again within hours. Went into the TV Sound settings and under 'advanced options' I was able to change the output format from PCM to Dolby Digital and that seems to have fixed the issue.

        I too have experienced this buzzing issue about 10 times since the s2 update. It is resolved by fully power cycling the beam which is really annoying and inconvenient. I’ve also performed a full reset but after a few days the issue comes back. One thing I have noticed is it is most likely to happen when using my Samsung TV’s built in YouTube app. When using other external devices - Nvidia shield etc, the problem does not present itself at all. This is clearly a really common issue judging by posts here and elsewhere. I hope Sonos can fix it as my experience up to now has been excellent. this has given me a reason to doubt their reliability for the first time.

          Hi @beaker1977.

          Welcome, thank you for reaching out to Sonos Community and providing a diagnostic report since this issue is really annoying let me try to help you out.

          First, can you try to enable the wifi connection to your Sonos beam?

          Next try unplugging all Sonos devices from power, then reboot your router. Once the router comes back up, plug your Sonos devices back in.

          Let us know if it works. If you need help with any other information, please be sure to let us know.

            Thanks Mark. I’ve followed your advice and enabled wifi on the beam, unplugged all my Sonos devices, rebooted my router and plugged everything back in when the router was back online. If the problem re-emerges I’ll let you know but so far, so good.
