High pitch playbar noise

I just installed my new playbar and have the same static sound coming from it. Tried to switch off all other appliances to see whats causing it but the hisss does not go away. Ran a diagnostic 4636612

Also in australia 🙂

After my discussion and troubleshooting with technical I received my replacement item today.....which has exactly the same issue as the first one. It too shall now be getting returned along with the original and the subwoofer. I've now lost faith in this product , as an electrician I've checked all possible avenues with regards to interference and such that may be causing this issue, and have found nothing.


In a room on its own with only the power lead attached it has this annoying whistling/buzzing sound coming from the right hand side speaker


Hopefully SONOS start looking into this more, as it could be a great product other than this very annoying issue affecting some customers.


Good luck

We'd definitely like to take closer look into this with you. If you haven't sent back those PLAYBARs yet, would you be able to hold on for an extra day first?

I've gone ahead and updated the right team and they'll be reaching out to you shortly to setup a call if you'll be available. 

Sure no problem, I had them packaged up ready for pick up tomorrow but I've just unpacked it again...would really love a solution but I'm at a loss I'm afraid.

Great, thanks Kevin. Do you mind sending the serial number for the replacement one in reply to that email ticket you have opened? We'd like to look into that one as well but it isn't liked with your account yet.

I've just linked it to my account now.

It looks like the first one was just reregistered, that serial number ends in 74:25:E. Did you add the other as well?

Apologies, I hadn't bothered registering the second one due to it making the same noise as soon as I powered it up....I must have mixed them up when packaging them...I 've just registered it now for you....noise so far appears to be gone although was making it as soon as I plugged it in again.

Edit....noise is back.
