Sonos beam gen 2 issues

Sounds rather strange? What audio source were you playing when it happened on each occasion, was it music, or a TV audio source? I think it’s best to try to submit a diagnostic (noting it’s reference) if you encounter the issue again and maybe capture the sound on video for Sonos Support to investigate further.

Thanks for your reply Ken, the first time it happened there was no source, I was connecting to the TV via the HDMI eARC connection but had not yet plugged this in therefore this rules out the hdmi cable. The 2nd time it was watching TV but the programme had been paused for a few minutes so no sound has been played through the speaker on both occasions. Other than these times it has been fine. My main concern is this happens whilst I’m out and the dog is in the house by himself as it’s unbelievably loud as you can imagine.

The reason I asked about what was playing, is this site here that refers to a different brand of Soundbar makes mention of a similar noise, but puts it down to an incompatible signal being received from the TV.

TV’s these days have audio pass-through on their ports so it might be a device connected to the TV is sending some kind of unsupported signal - do you have other devices connected to the TV? If so maybe the diagnostic will show where the sound is coming from and help you get to the root cause of the matter (er .. perhaps?) 

Yes mate it’s a good shout, I’m an engineer so fully understand your reason for asking as any kind of data can be used for troubleshooting the issue. I have skyQ but on this occasion I think the issue lies in the beam 2 itself as the only attachment it had the 1st time was its power cable so was not connected to any source at all at that time. It had been connected previously via the optical port on the sky Q box as the hdmi provided was not long enough to get to the back of my TV. I’m going to try recreate it today to get a video as mentioned for support.

Thought I’d update this in case anyone else comes across the same issue with their units. I got a video of the issue, got in-touch with Sonos and the suppliers who were both really helpful and suggested a factory reset as it’s an issue they have never come across.

Completed the reset with all my devices and set the system back up. No issues for roughly 24hrs then unfortunately reoccurred. The beam gen 2 is now back with the supplier for testing and they have offered an exchange.

Just had exactly the same thing happen. Not a nice sound and the only way I could stop it was to unplug the beam gen 2 as the S2 app couldn’t connect.  I’ve had a number of issues since getting the Gen2. Loud clicks in the surround 1SLs when navigating menus on Apple TV 4K.  

Same mate I just unplugged it, and it’s very unpleasant, I have a pup who is left at home now and again and my main fear was it happening when I was out. I never had the clicking on the SLs but did notice like a buffering in the sound from the rears at times. Where did you get it from? I’d recommend returning it and trying again. 

I had the same issue yesterday literally within minutes of turning on my Beam 2. It happened twice so I called support and sent diagnostics. The rep said that my diagnostics showed interference and suggested switching my internet channel or hardwiring the Beam vs. using wireless internet. I have hardwired it and have my fingers crossed.

I can confirm that using wired internet does NOT fix the issue. Returning it.

I have had the exact same experience. No fun. Was just listening to some music.
