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.

If it’s any help, but slightly off-topic, I’m having a similar issue intermittently with my PlayBase since upgrading to Sonos 2. I’m using a TOSlink connection from a Sony TV. The audio format is Dolby Digital 5.1. The set top box and TV are connected via HDMI (non-ARC).

I have the problem only when watching PBS stations. It goes away if I switch to a non-PBS channel but returns when I switch back to PBS. It goes away on the PBS channels as well if I put the TV and STB to sleep then wake them up.

Could it have something to do with the way British TV programs are re-encoded for broadcast in the USA?

It's set to auto sound everywhere.

Like the post above, it's only on YouTube and Netflix so far, it will play music and TV fine, but if you go back into those services it will buzz again until powered off.

Also YouTube and Netflix have a different buzz.

If there's anything else I can test to help, let me know

I have had the exact same issue 3 times since the S2 update, though I'm yet to grab a diagnostic of it happening.

I have a Beam connected via HDMI Arc to an LG TV. In all 3 cases it's happened when using the Prime Video app on the TV itself (although even this doesn't happen every time).

Turning the TV off stops the buzzing, but as soon as the TV is switched back on again the buzzing returns, even when just viewing a menu. Similarly, unplugging the TV from the mains and plugging it back in again, as soon as the TV is switched on the buzzing returns.

Disconnecting and reconnecting the HDMI leads from both ends doesn't fix it. As soon as the HDMI is reconnected the buzzing restarts.

As others have mentioned, if I switch the TV off and then get the Beam to stream some music, it sounds fine. Turn the TV back on again, and the buzzing returns.

The only thing that fixes it is pulling the mains on the Beam.

I have a Sky box and a PS4 plugged into the TV via HDMI too, and have tried disconnecting these in case the TV is trying to pass nonsense from one of those (both are on standby), but again the buzzing continues.

I had no issues of this kind with the S1 firmware so can only assume that the S2 firmware is causing the issue.

Same problem as described in various comments here.

Music plays fine without the buzzing but once the TV (Samsung QLED) is switched on, the buzzing starts even without opening Netflix or Youtube.

Sonus seems to have gone quiet over this issue. Please could we all have a further update.

So this happened to me again this evening when using the Amazon Prime Video app on an LG TV. Specifically it happened when I paused the programme and attempted to seek back a few minutes.

Once the buzzing started it continued even when closing the prime app and switching on the Sky box. Anything that used the HDMI connection the buzzing was there.

Unplugging the Beam was the only fix.

This has happened to me a couple of times with Beam connected to Samsung ks7000 via optical cable.

Pulling the power fixes it, it doesnt happen 99% of the time - v odd

I have the same issue after updating Sonos. LG TV, YouTube, loud buzzing. It has been continuous. Tried disconnecting and also turned off the Quick Start option as mentioned, but buzzing still happens.

I can confirm that as well as seeking backwards in the Prime app on my TV triggering it, I too get the issue when using the YouTube app.

Today my wife and kids resorted to simply unplugging the Beam and not using it. It's turned into a rather expensive ornament.

The Beam is the only Sonos product I own, so there's no tangible benefit (as far as I can see) to me using S2. Is there a way of simply rolling it back to S1 firmware? I suspect that'll fix it.

I'm now also getting issues with the sound not playing when I turn my tv on. I have to pull the HDMI Arc cable then reconnect it. This has happened 6 times in the last 10 days.

Also, it seems Sonus have turned their backs on this issue for the time being as I've not had an up date in over a week. Over £600 spent on Sonus equipment since last Christmas and all the problems started after the S2 update.
