High pitch playbar noise

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.

I bought the new Sonos "playbase" and every time I turn on my television the first time in the day or play music after a few hours (essentially if the Sonos playbase is in sleep mode), I get very loud screechy sounds. The only way this gets solved is by disconnecting the speaker from the power outlet for a while and rebooting it.

This is a new installation. Diagnostic number 7302556.

It just happened again. I tried playing music on it after 4 hours approximately from my phone this time and not the TV and it started giving large amounts of static along with the music. I sent another diagnostics report while this was occurring - report number 7303950. The problem goes away if I unplug the speaker and plug it back in.

I have been trying to call support but not getting anyone on the phone.

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

If you don't get a timely response here, I suggest you phone Sonos Support. Your PLAYBAR has a hardware fault.
