Hi

I have a buzzing sound coming through my playbar - 1st gen.

It appears to be from the source (tv) as I was not getting it on Spotify.

I have changed the optical cable. Still getting it.

My sound settings are set to PCM.

Once I turn tv off it remains for a few seconds before continuing. When I reset by unplugging power it disappears before returning again.

Any assistance appreciated.

Hi @alphajericho, thanks for the update and for sending a diagnostic report of your Sonos system. upon checking, it shows that the speakers show offline but when I opened the diagnostic results. it doesn’t detect any issues on the Playbar. I’ll ask you to take a video proof when the issue is happening and kindly contact our phone support team for further assistance and more in-depth troubleshooting steps. They’ll ask for the video proof and additional troubleshooting steps and options for this issue.

Let us know how it goes and we're here to answer any further questions you have.

@vilini Do you have another power strip/surge protector you could use? Also, move any other devices away from the Playbar.
