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.

    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!

    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.

    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 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!

    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.

    We’ve been having this problem for over a year with a Samsung TV / playbar attached via Optical output.  Youtube seems to kick it off - tis always fine until then and the only thing that fixes is turning off speaker at power and reconnecting

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

    What did Sonos support say when you called them?

    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?
