Hi all. There’s a update today on the sonos app. Hopefully this might fix the issue.

So I haven’t had any issues for 4 months and literally just now the buzzing is back all of a sudden! Does anyone know if there has been a software update to the play bar? 
 

thanks

I have the same issue with my Samsung Q7.

Sonos actually sent me out a new Beam but as you all know, it’s an issue with all of the Beams. 
Still have the issue after about a year now with no one at Sonos able to resolve it. Pretty poor.

Soundbar user here. I get the occasion humm while watching YouTube on a Samsung smart TV. 
For me, it only seems to happen on low quality home shot videos. For example “shower won’t turn off (shower cartridge replacement)” triggers a hum on the sonos for me. 
Is there any chance these low quality videos are formatted in a way that it’s throwing off the Sonos?

I has this on my Playbar a few weeks back, only remedy was to unplug the Playbar and reboot.

Once it had acquired the buzz it was present on every TV source.

Very odd!.

My setup has been the same for over two years.

Purchased the beam yesterday and it worked great… then this morning it did a buzzing sound as soon as i tried to watch something. Very concerning

Hello @pghalliday,

Welcome to the Sonos Community and thank you for reaching out with your issue. 

Are you able to see or adjust what audio format the YouTube app is playing through to your TV?

Is the TV set to output a specific format via HDMI/ARC or is it set to automatic?

Please double check that the format is supported by your Sonos Beam and if it is still occurring, please submit a diagnostic report and include the confirmation number in your reply.

Hello @flyingpadrejr, @Vosabhoy and @Jrdncrtr 

Have you been able to look at the settings I mentioned in your TV?

If the issue is reoccurring after rebooting, please submit a diagnostic and reach out to us with the confirmation number so that we can assist you further.

Changing the settings on my LG tv doesn't resolve the issue, only pulling the power cable then reconnecting it solves the issue. This has happened twice since updated my app. Diagnostic...347288406.

Hey there, 

I’m not seeing correct formatting on either of your home theater systems.

@Vosabhoy, if you are using the optical adapter with your Beam, check that the TV is outputting either Dolby Digital or PCM as a format to the optical port.

If those settings appear to be correct, try rebooting your TV (unplug it from power) rather than your Beam and see if this changes anything.

 

@Murpa, I’m not seeing any connection data on your Beam at all. Is your TV on and is the HDMI cable firmly connected on both ends and in the ARC port?   

Hi Jean,

Sorry, I thought the diagnostic would show what was happening before I disconnected the HDMI cable...  Diagnostic with the buzzing - 480665001

Having same issue with Samsung TV. Just started today. Pretty constant and I get buzzing and/or a high pitch tone intermittently as well. Pretty annoying, had to just use tv speakers and thatsounds fine.

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.

Hi, I have checked the settings, made some adjustments an ran another diagnostic 130887713. 

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.

I’m getting this issue on my playbar since S2 update. Only way to stop the buzzing is to reboot the playbar. When it’s buzzing it’s present on any source. So annoying!

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…..

 

Have you tried to call Sonos Support directly to discuss it?

When you speak directly to the phone folks, there are more options available for them to assist you, certainly much more than the community here does. 

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. 

1 page and a couple other threads vs. 100 pages+ and dozens of other threads.  I know where I'm putting my money.

Same has happened to me last week (only once), and was fixed by pulling the power chord.

This is only a temporary solution as it happened again with me 2 days later. Definitely down to the Sonus 2 update.

Hello @Murpa,

Since your set-up does not include any bonded surround speakers, switching your audio format to PCM (or Stereo as @Ken_Griffiths points out) was going to be my next suggestion, you just beat me to it. 

Please keep us posted on if this resolves your audio issues.

@Vosabhoy, are you able to set your TV audio format specifically to Dolby Digital rather than PCM? Previously the TOS link status on your beam was “inactive” which is why i suggested rebooting yoru TV along with checking on the specific audio format.

Most of the issues I’m seeing with home theater audio have to do with the TV not passing the correct codec on to the Beam and then chaos ensues. Whether this is is a purely “local” issue or something tripped by the update and adjustments made in how we are processing the signal, I am not sure.

Hi, the options are PCM or auto for digital sound out via HDMI ARC. I currently have the setting at auto.

Getting an identical issue on my Samsung TV. Only happens w/sound over HDMI-ARC, not streaming, so it’s not the speaker.  Just noticed it today, everything was peachy until the Sonos 2 update.  HDMI ARC set to PCM.

 

Diagnostic 1305211937

Same issue here. The beam makes a buzzing and popping sounds intermittently when the TV is off and there is nothing else pushing sound through it.
In my case I noticed it first when I replaced my TV, not the sonos software. Just upgraded my TV to an LG C9 and I’m using eARC for the first time (I was using optical before). Resetting the TV does not do anything to fix it. From the TV’s HDMI ARC options, I can only select PCM, Pass-through, or Auto. The only option that works (produces any sound at all) is PCM, so that is what I selected. eARC is On. 

i just submitted my diagnostics: 700268017
