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,

    I was having this issue too.  Tried the EQ Reset as well as a different HDMI cable - neither resolved.

    Submitted diagnostics to support, and they said it showed nothing clearly wrong.  Support suggested…

    “Can we reboot the Beam to clear out the cache on it? Unplug the Beam off from power for 30 seconds then plug it back to power.”

    That resolved the issue (for now).

    Support said…

    “ Rebooting the speaker also help clear any possible issue on it, since it was powered on for 23 days and it did an update. The cache seems hit it limit. Kindly reboot the speakers for time to time to clear the cache on each one.”

    Hopefully this helps a few folks avoid the hassle of a full factory reset.

    I am running S1 and I have had exactly the same problem. Switching off both the TV and Beam at the plug point resolves it but it can happen on consecutive days or then a week apart.

     

    I assumed it was the TV which is 5 years old or the cable which I was going to replace.

     

    Interesting to see if the next update whenever that is,  resolves it.

     

    Cheers

    I am also having the buzzing sound. I turned it off and back on and the buzzing stopped.

    Same problem since S2 upgrade. It was much worse (louder) the first time it happened a few days after the update. I power cycled it (turned it off and on) and that resolved the buzzing but it has been back 2-3 times since. On each occasion I power cycle. Very frustrating and hope this gets resolved in next update.

    There’s multiple thread with these issues. I have a beam and 2units Sonos 3. 
    Issues can only resolve if I power cycle it. Can someone acknowledge and work on this!

    Only happen after the S2 update recently. It’s definitely a firmware issue

    Sonos Beam is buzzing out of the left front speaker. I first had this happen a week ago, and I thought it was the HDMI cable from the tv to the speaker. I ruled out the speaker as it was working with Sirius XM/Amazon music when not using the HDMI cable. I changed out the cable and it started working with no buzzing for about two days. This morning, it started buzzing again. There is a problem with the Sonos 2 Application or the speaker. There are multiple people on your community forum with the same problem. I also tried the factory reset, it did not work. I’ve had no issues until this new application. Please fix the problem.

    Same issue with my Sonos Beam. I updated to S2 two weeks ago. I noticed it while painting and listening to YouTube through the Beam. The buzzing noise doesn't happen when streaming Netflix.

    Beam still on S1 here and having a similar problem. High pitched buzz continuous when TV is feeding audio via HDMI ARC. Spotify audio fine. Same issue after power cycling screen. Reseating HDMI cable results in same problem. Temporarily resolved by power cycling Beam. Had it at least 3 times over the last month.

    Same problem here.

    Had it even before S2.

    Today our TV had a update, and the problem came. rebooted the Beam and it helped for about one hour, then it was back again.

     

    Switching from auto to PCM as suggested did not solve it, but made the sound much higher pitch (very unpleasant!).

     

    The TV is a LG OLED. Seems there is many with those. Anyone experienced this on non LG tv’s?
