High pitch playbar noise

Had my play bar for just over a month now and had it installed on the wall yesterday and i am getting the same high pitched noise all the time - tried factory reset & tuning off the white light but makes no difference any other ideas? or will i need to run a diagnostics and call support?

It sounds like you'll be best off giving us a call. Thanks.

Purchased a Playbar and two Play 3's from John Lewis yesterday.  All set up fine (although not yet with TV - which arrives next week) and was very impressed with performance and capability.  Until I closed everything down via the controller and noticed the ongoing high pitched tone coming from the Playbar.  So Googled the issue and found this and a couple of similar older threads. 

Have mains power cycled the unit 3 or 4 times, experimented in two other rooms, left it powered up overnight, and tried it connected directly to the router - but all the same, and the tone will not go away.  With volume turned down, it is noticable with music playing through the unit.  Seems to originate from centre left of unit?  Haven't tried a Factory Reset yet, as that seems to have done nothing for others? 

Frustrating, because the capability and performance of the system otherwise is really impressive.  Others with the problem seem to have simply returned theirs for exchange or credit.  But given this seems to be both a longstanding and ongoing problem - what liklihood that a replacement unit will be any different? 

Ryan - Could you advise if you want me to run the diagnostic and submit, or call UK Support No for further advice, or return to John Lewis for a replacement in the hope that a further unit will be better?

Serial no of my Playbar Unit is - B8-E9-37-70-A5-9E-E. 

I got mine from john Lewis with high pitch sound and then swapped it and my new unit is completely fine in fact awesome. Don't mess about with all these tests they will not fix despite sonos being aware of the problem. Frustrating but worth the wait

We're trying to narrow down what's causing this and would like to get diagnostics and run a few tests. If the PLAYBAR is indeed affected by this issue we're happy to setup a replacement and make sure to get these PLAYBARs back to our hardware team to investigate further.

I'd recommend either giving the UK Support number a call or taking it back to your reseller, John Lewis, they'll both be able to assist you in replacing that PLAYBAR. We prefer in this case if you can work with us to diagnose and replace if necessary.

Thanks Ryan and Matthew

Ran diagnostics yesterday - Reference No is 3969530.  Have also noticed that if you stop the digital data input but leave powered up, and then increase/decrease the volume control via the slider on the controller or the rocker buttons on the unit, the pitch/characteristics of the high pitched tone is variable.  So something associated with the power supply unit or amplification hardware? 

Contacted UK Support line today and they confirmed that the unit should be returned to the retailer for exchange.  So will return unit to John Lewis this weekend for exhange, and hope that replacement is problem free.   

This problem aside, I am very impressed with the capability and performance of the system.  To the extent that coupled with the pair of Play 3's, I'm now doubting the need to put a Sub on my Christmas list for our needs in this room set up.

Got a new one from Hifi-klubben here in Sweden. Works like a charm! Now I am a happy camper again.

Same issue here, bought on Saturday just gone and tried all the advice above but constant high pitch unbearable whine when not in use. When in use slightly more bearable but still present. Next step please Sonos!?!

The next step is going to be to give us a call so a technician can help get you all sorted out. We may need to replace that PLAYBAR. You can find our contact information and hours here.

Thanks
