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

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.

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.

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,

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

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.

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

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.
