shrill whistle coming out of the playbar

Hello people, 

  Since I moved and plugged my play bar  into my Samsung smarttv ,  it makes a  Screeching noise  as soon as I power oN. It is not related to the  optical ,  because even if I removed it,  the noise persists. 

 

(Sorry for my English) 

 

I hope someone can help me. Thanks 🙏

    Sometimes such noises may come from a faulty switched-mode power supply, as built into the Playbar. I would first submit a Sonos system diagnostic and post the reference back here and then contact Sonos Support via phone to discuss the matter with them direct.
