High pitch playbar noise

Thanks for the update. I'll add it to the notes here for you. 

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.
Thank-you....also sent the serial number via the open ticket.

Hey all, I seem to be having the same issue - diagnostic : 4629345
Hi all, After 5 days of noticing the high pitch sound getting quieter I'm happy to inform you that it seems to have gone. I'm not sure if this was 'bedding in' as some other customers have described or something else. For those who are interested in how I've used the soundbar: - it's been powered on for the full 5 days - I've played music and TV at different volumes, sometimes very loudly and others and a low volume - it's has 2 satellite Play:1's (I'm not sure how that would make a difference) I'll keep my eye (or ear) on it over the coming days and report back if I notice any difference.

I've just plugged in my new playbar and was very, very disappointed with the terrible high-pitch noise coming from it.
Even MORE disappointed to find out this is apparently a KNOWN issue, and still this unit was sold to me as being "high-end" top-of-the-line. Currently it's basically useless.

Hi NL_Stijn,

We've seen some PLAYBARs with a high pitched whines, though it's quite uncommon, they do pop up from time to time. In most cases it's a hardware issue with the unit which we'll help with. I'd recommend giving us a call on our support line to get that unit sorted out quickest. You can find our contact information and hours here: http://www.sonos.com/contact

I had exactly the same thing with mine. I messed about with it for a bit, did a factory reset, left it blasting music for a couple of hours etc, but it was obviously a hardware fault.

Took it back to the store the next day and they swapped it for a new one, which is fine. I mentioned I'd Googled it and that it seemed to be a known issue, but they said it was the first one they'd had returned with the problem.

Hi, I bought SoundBar and it makes a high pitch noise continuosly, Please advice. Thanks

Add me to this list. I went out yesteray looking to replace my 'non-subbing' Samsung sound bar with a Bose Cinemate. However after being 'persuaded' in-store to consider a Sonos, (I had been considering moving 'up' to Sonos eventually anyway) took the plunge and decided on a Playbar AND Sub.

Saturday night, everything was rosey even to the point that the Sonos Twitter feed favourited my .... Wowser! Tweet. Come Sunday morning however and I thought I'd developed tinitus. Oh no it's coming from my new sound bar. No other hardware close enough to cause issue, lets have a look on the Sonos support site, low and behold type in 'high pitched' into the search bar and 30 threads returned.

To say I'm disappointed is an understatement. I've already been in touch with the retailer (Hughes TV and Audio) and they are supplying a replacement bar when my Play 1's are delivered on Wednesday, so fair play to them.

Watch this space.

Add me to the list - I am very disappointed in Sonos as searching on Google brings back HUNDREDS of posts about this issue on the Sonos website dating back 3 years.

Thankfully I have purchased from a good retailer who will happily swap at y convenience, but I have to wonder now whether to swap for something else or keep the Sonos.

Seeing so many issues does make you wonder about quality....

Yeah I feel the same way about humans every time I go to a hospital...

I don't mean to be rude but that's a daft thing to say, Sonos are making MILLIONS of speakers every year, it is impossible for every single one to come out of the factory absolutely faultless. You were unlucky, it happens, no point being so dramatic about it, take it back, get another one, make sure they test it first.
