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

Fixed by changing digital out from tv to PCM instead of auto

That just switches the TV audio output to stereo, rather than Dolby Digital surround sound (when available). 

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.

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

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.

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.

Hi Jean,

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

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?   

I have the exact same issue (beam+lg tv+buzzing) but only since this evening.  I'm using the S1 app and have the HDMI arc set to auto.  A reboot of the beam gets rid of the buzzing temporarily before it restarts.  I've unplugged it so the rest of the family can watch TV.......  Diagnostic 172347447

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.

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.  

 

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.

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

Same issue with beam connected to my LG tv. Loud buzzing noise have to pull the power cable then reconnect. All since Sonus 2 update. Not impressed!!!

Hey!

 

I’m literally having this exact same issue, pretty much word for word. Same tv, same app setting it off, same setup. Did anyone find a fix?

cheers,
