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,

Hi
Welcome, thank you for reaching back to Sonos Community.
Glad we can help.
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.

Hi
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.
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. Diagnostic - 1868961579

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:
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.

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
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 🤬

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 😏
😕

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?
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 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.
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.
Had beam for over a year worked perfectly. Update to S2 buzzing started. Same tv, hdmi, router … only change was app. Fix it Sonos your rep is on the line.
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
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.
I am also having the buzzing sound. I turned it off and back on and the buzzing stopped.
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 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.
so the plot thickens...i got my sonos replaced under warranty ....two weeks in and buzzing starts again on my brand new system...i have sent diagnostics of no....1687051048..so something tells me this is a software issue 😡😡😡
Diagnostic created 502967541
Yep it comes back...
Ah, of course now that I have a lead (gathering support information etc.) I can’t get it to buzz anymore :-)
Yesterday I’ve watched something via Smart share without problems, then some IPTV. I don’t know if the Smartshare session sorted it out or what was it, but for the moment I can’t reproduce the issue.
If you do manage to figure out a reliable repro for this, please let us know :) A diagnostic as soon as the buzzing starts would also be helpful.
