Sonos Sub Gen 3 crackling/static sound

Update: This was only a temporary “fix” of the noise issue. The noise is back - so the trick with wired connection did not help :-(

I really look forward to a real fix.

Agree, Sonos need to respond to this problem. Even if wiring sub solves the issue it does not feel ok to me. If users cannot use Sonos’ speakers wirelessly they cannot market their products as wireless speaker systems.

I too have the same issue - I bought my Beam, Sub and 2 x One SLs for a home theatre set up in November. The original sub had this humming issue in which a replacement was sent out to me very quickly. The new sub which I have received still has the same issue but only when I put my ear in between the gap on the sub, and even then it is a faint hum, where as before it was that loud I could hear it 2 metres away.

One thing I have noticed is that it stops when streaming music from Apple Music, but happens when audio is received from the HDMI connection...

Received mine today. Same issue with a hissing/electric sound, mostly can be heard when you have music playing and turn volume to zero, but also audible when you sit close to the sub and volume is lower.

Will need to replace if there’s no other way to fix it. Following to see how Sonos handles this and if it makes sense to replace now or later.

Version: 12.2.2

HW version: 1.32.1.4-2.1

Series: A200

Sounds good otherwise, but this is unacceptable.

System: Arc + 2 x One SL + Sub.

I ordered mine a few days ago as I was waiting for the Gen 3 to get back in stock. Seems that most places sold out over the holidays and both the Arc and Sub gen3 are in backorder with Sonos UK. 
 

i’m hoping they have sorted the issue. Sonos website says it won’t ship until the end of the month. I’ll report back on whether it still has this issue. I have a couple of Gen2 subs to compare it too. Not noticed any noise from any Sonos speaker in the past and I have over 20! 
 

At rhis price point there really should not be this kind of issue - and since the audio internals are largely unchanged the should be no excuse for this not to have been picked up in QA. 
 

Fingers crossed! 
 

as the only reason I’m getting it is to try out the ‘2 sub’ feature. If the fault is still there then it’ll be sent back in the returns period. 
 

PS: excellent work by the early adopters to demonstrate the issue! Thanks. 

Received my replacement Sub3 from Sonos today. So far so good. 👍

that encouraging. Hope it lasts. Keep us posted.  

My Gen3 Sub has just shipped. fingers crossed the issue is resolved! Will know soon enough I guess. 

Good luck. My replacement unit hasn’t given me any issues so far.

My replacement Gen 3 sub has also been without issue. Good luck.
