I occasionally get a loud buzzing over the audio from Beam connected with HDMI


Userlevel 1

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.

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.

Have exactly the same problem, happens every time the adverts come on when watching something on ITV Hub. Only remedy is to reboot the beam. Very annoying! 

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

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.

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 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.

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 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.

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

Same issue here!  Sonos Beam, Sub gen3 and (2) Ones...Noticed the buzzing and hum always  and only transpires after extended YouTube video surfing.  But, once it starts it carries over to each and every source after that.  Only fix (which has worked each time) is to power cycle the Samsung TV.  I have tried switching to optical and swapping HDMI cables to a very high quality Crestron cable, to no avail!  I must power cycle TV...only had the Sonos deployed for about 3 weeks now...happened within the first 2 days and couple times since.

Hello there.

I’m having the same problem. Sonos beam connected to two Sonos one surround speakers, worked perfectly until about three weeks ago than loud constant buzzing when connected to the Samsung 75 TV via HDMI-ARC. No extra noise when use with streaming music such as Apple Music.  Currently totally unusable with television. Thanks

Maybe consider temporarily switching the cable connection to the optical-out port on the TV using the optical adapter that comes with the Beam and see if the buzzing stops, if so, it might infer the issue is with the TV, if not, then try a different HDMI cable and if the problem persists, then submit a Sonos System Diagnostic, posting its reference back here perhaps for the support staff to take a look at the data, or you can contact Sonos Support HERE.

Unfortunately the same is happening here. I only use the beam, no surround or whatsoever.

Hi,

I have the exact issue. It started few months ago, with occasional buzzes (solved by unplugging all speakers - i have a 2.1 setup with Beam and two Sonos One) and from yesterday, it’s permanent. I had to remove the cable from TV. It’s connected to a Samsung TV via HDMI ARC. I tried to change the sound output settings, nothing solves it. I tried bitstream, pcm, everything. Music via Airplay, Spotify or other music services works ok. The only issue is with TV. It doesn’t matter if the source of TV is Netflix, YouTube or Live TV, it buzzes. Sonos diagnostic report 393408273.

 

Thanks,

Costin

The same is happening with my sonos beam as well. Very disappointing ☹️  Diagnostic is 1588770432

Can someone at Sonos take a look please as it keeps happening and is really annoying? Cheers

Happened tonight again. Playing from the Channel 4 app (in the UK). It's more of a continuous tone from the right hand side of the speaker. I powered off and on which cleared it. Diagnostic 1659162737. If someone at Sonos could take a look please?

Cheers

I too have had this issue twice in the last month from my Beam and I'm on S1. There's been a buzzing from the right hand side of the speaker outputting from my Samsung TV (radio and other music sources were fine though). 

Oddly it was fine from Netflix or Amazon using the TV apps but the Channel 4 app and TV channels played from my Virgin TiVo box emitted the buzzing.

 

I switched off TV and TiVo which eventually sorted it so I was convinced one of those was the problem. Reading this, it sounds more widespread so I'll submit a diagnostic next time.

 

same issue with my Beam .. I have only noticed it recently… samsung TV ARC connected BEAM connnected via LAN… HDMI input coming from a Orange LiveBox 

 

it seems like the left hand side is buzzing and all the sound comes from the other side…  unplug/replug resolves it but it comes back ?

 

this must be a software issue...

Hi.  I am having the same issues. Samsung TV,  Playbar with two play 1 and a sub using S2.  First time it happened was three weeks ago and it kind of resolved itself.  It came back last night and I had to unplug the playbar to fix it.  Has anyone gone back to S1?  I’m tempted but want to wait to see if anyone has had success doing that.  Thanks, Jim

 

Hello all,

I'm facing the very same issue. My Sonos Beam gets a buzzing annoying sound after a few hours of being used (YouTube, Netflix), the only way to fix it is disconnecting the Beam from the power and then connnect it again.

It's connected to a Samsung smart TV through HDMI ARC port. This also started happening since latest app update, I didn't have any issue before this.

I see Sonos staff is now ignoring this thread, I was going to get a Sonos Arc, but after this horrible service I'm definitely spending my money somewhere else.

i have a beam and had the same issue. i factory reset it and it was working fine for 2 days and the buzzing noise just came back like 20mins ago. Darn.

Sorry to hear that. My Playbar has not buzzed once since I factory reset more than 3 weeks ago. This issue might be affecting the Beam in a different way.

I would like to report that I factory reset my Playbar 2 weeks ago and, since then, I have not experienced any more buzzing. Not sure if this is related, but for me factory reset seems to have solved the problem. The reset instructions are here: https://support.sonos.com/s/article/1096?language=en_US

I had this issue for the first time yesterday. My Beam was plugged into my Samsung blu-ray player using an optical cable. I was watching a YouTube video from the Samsung app, and it was working fine. I paused it, then when I resumed, there was a constant tone in the background. Playing the same YouTube video through the TV speakers was fine. I tried switching optical cables, and tried plugging the Beam into my TV’s optical output instead, but the loud tone continued as soon as any audio was playing through it. In the end I unplugged the Beam, plugged it back in, and that fixed it. I just hope this doesn’t happen frequently since the plug socket is hard to get to and there’s no other apparent way to reboot the Beam. Maybe there should be an option in the application to do so?
