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.

Happens with my Beam and One SLs.  Its loud as hell and I have to pull the power to get it to stop and reset. Only time I have noticed it is with Youtube playing on Samsung TV with HDMI/ARC.

What did Sonos support say, when you submitted a diagnostic after the event, and called them with that number?

Hi,

I also had the buzzing sound issue through the HDMI arc.

Problem first surfaced after Sonos app S2.

I managed to fix this issue through connecting my beam with Ethernet cable, then the buzzing stopped.

So maybe try this if you're having the same issue.

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 have the same issue. Just got my Beam 2nd gen, 2 ones and a mini sub. Happens only when I turn on the TV, not streaming from my phone.

Diagnostics #: 1682456909

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.

M

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.  

Z

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. 

J

Same issue here.  Beam, Samsung TV, Youtube sets it off.  Have to unplug the beam to fix.  Annoying

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