Beam Gen 2 - sudden full volume hammering sound

Hi everyone,

Last week I got a Beam Gen 2 + Sub Gen 3 to replace my Beam Gen 1. So far everything's been running smoothly. Then today when I was listening to music with said setup while working a sudden hammering sound interrupted the music. The noise must have been at full volume despite the volume limit which I set to 40%. I jumped up from the couch and instantly pulled the plug. Music kept playing in the adjacent dining room on a pair of One/One SL for a bit before it stopped.

I tried to find the problem online and only found this video. This is exactly what I experienced with my Beam as well. However, this video does not give a good idea of how loud this really was.

Since I couldn't find a solution online, I called the support hotline. The lady on the phone told me, that such a problem has not come up yet. She asked me to replug the Beam and let some music play. After just a few minutes the noise interrupted the music again. So at least the support lady had some impression of it and I managed to send a diagnostic while the noise was on. After a few seconds the noise stopped. She then instructed me to reset the Beam/Sub setup and couldn't really help me otherwise.

Anyone here experienced this problem and possibly has a solution or knows what's the reason for this issue?

@Staff please help me out. This is really creeping me out as I feel this could come up again anytime... No fun watching movies or listening to music this way. My neighbours must hate me now.

Thank you.

2nd time it happened now. Ive purchased this thru the military base; had it for 6 months now. Great sound when watching shows and movies.

Then the deafening MACHINE GUN sounds;

1st time was at 3am, I woke up running out of the bedroom trying to figure out whats going on. Woke up our 6yr and 3yr old kids, crying and horrified.

2nd time is today, both kids ran to the bedroom terrified and the 3yr old ran so fast he couldn't control himself and hit the door knob on his head.

The sound was deafening machine gun sounds, FULL BLAST even though volume of movie being watched was only 30%.

I do have PTSD from the war and I hate that feeling.

Sonos need to fix this asap!

Wow, hard to believe this thread dates back over a year ago… I’ve had my Beam 2 for 3 months. I have personally had this experience for the third time and I can’t bring myself to plug it back in. This last time I had trouble getting the cable out and so I was lingering near the speaker for a few seconds fiddling with the cord and now my ear hurts hours later. I dropped my plate of food. And I wasn’t even using the sound bar or tv… just sitting on my couch and thought I was under attack. Even after experiencing it before, nothing can prepare you for 100db out of nowhere during pure silence. It's also happened while playing music for a party(embarrassing) and while watching TV.

Sounds like this isn’t an issue that is resolved by replacing the unit and frankly I don’t want to experience this ever again so I’ll be returning it tomorrow. Hard to believe this issue has been going on for this long and there is still no solution. Had heard great things about SONOS so I'm really disappointed.
