High pitch playbar noise

I see someone has attached their diagnostic to their message. So here's mine - 5505712. Hopefully this'll speed things up a bit.

hi all,
just to say that i bought my sound bar about 2 years ago, i move recently to another country and high pitch noise started on the playbar.
i reported it last week and i will receive my unit this Monday. and it took that time because DHL have been messing things up, if not for them (or let say a more effective service from them) i would have received the unit this week.
i am posting just to praise sono support on this one, they were very quick to respond and send me the replacement procedure.
thank you sonos! 🆒

Thomasl72,

Have you done what MaxP posted above, i.e posted a diagnostic? Once you do that, and they look at that, you're much more likely to get a message like his "contact our customer care team" post regarding a replacement, if it's needed. But it's possible that it's not, depending on what data is in the diagnostic.

I have the same problem.Mine is 3 years old. it has not been powered on for 2 months due to house restoration. Now when I start all SONOS stuff my playbar has this noise described above.
Anything that helped?
I have tried to move it, removed the spdif.
Here is my diagnostics: 6810035

Hi, I have reviewed your diagnostic. Can you unpair the PLAY:3s from the PLAYBAR and try again. Let us know if you still hear the noise.

Hi,
Have you had the time to look at My latest diag? 6811085
Still the same problem.

Hello. I'm having the same issue. Quiet high pitched squeal emitting from the left side of my Playbar. I'm in Adelaide Australia. My diagnostic code is 6922963.

I'm absolutely loving my Sonos rig and my entire house is now full of them, hoping I can get the Playbar to operate at the same high standard as the rest of the gear.

Hey janjensen, I've done the same thing for you. Your case reference is 170105-000591. Again, just send me a reply to the email.

I've just joined the high pitch noise club. Straight out of the box whilst playing music, TV sound or on standby. Still there with every other device in my living room switched off. Guessing it's a fault with the playbar as my play 1 speakers are dead silent on standby.

But reading the forum it sounds like it might be going back for a replacement.

I just bought the PlayBar yesterday and have the same problem, a high pitched whine from the left hand side. Diagnostic 7191339. I think I'll return it to the retailer for a replacement.

Hi, looks like you've already gotten your replacement, let us know if you have any trouble with it. For cases like this, you're always welcome to give us a call on our support line to confirm, but odds are the unit needs to be replaced. We're always happy to take a look for you.

Hi Aroosh

Welcome to the Community!

Thanks for submitting the diagnostics

A couple of questions :

What is the make and model of the TV you have the Playbase connected to?

If you have another source of TV with an optical output ( Apple TV, Games Console, Cable Box etc) could you connect the Playbase directly to the source and bypass the TV and see if the issue still occurs?

There is a fair amount of wireless interference in your environment, but this shouldn't cause any artifacts in the sound, it could cause the sound to drop out, but not produce any abnormal sounds.

Do let us know how you get on.

Many thanks

Hi I have a low volume high pitched sound emitted from my PlayBar. I've followed all the guidance on this blog and would appreciate you assistance on diagnostics 7480338

Hi gnewman,

Just finished talking with Mike W. at Sonos Customer Service re: high pitched sound coming from my Gen 1 Play 5.
After sending in diagnostics code, factory reset and then an hour on the phone (confirming serial number, etc) I am being told that only option is to pay another $250 and exchange my Gen 1 Play 5 for a Gen 2 Play 5....meaning I am into my Play 5 now for $750...ridiculous! Unit is 3 years old....Quality audio gear is supposed to last longer than that. I understand warranty is past and have no problem having item repaired or replaced at a "nominal" cost due to this hardware defect.....$250 in not nominal.

I was also told that it is mandatory I send in my Gen 1 Play 5 so it can be reconditioned (and sold again?)...or else my credit card will be charged an additional $500 (on top of the $250 exchange offer)

Not happy about this. I have 3 Play 1's, a Connect and Play 5 with plans to buy more for our pool area and other rooms....not any more.
Also calling BBB and local consumer fraud TV/radio/paper....this manufacture trying to get out of repairing/replacing a $5 hardware defect and capitalize on existing Sonos customers. (saving this post to show fraud alerts incase Sonos deletes from thread)

Picture of devices near by. Buzz even when they turned off.
