Hi Heiner
My Sabre V3 gn3 (https://shop.max2play.com/en/audiophonics-oled-raspberry-pi-display-bundle.html) just got it before few days.
the noise come frome my speakers only when no music playing.
these noises come from the output device when power on and no music. when music start no noise, also sometimes click noise when change music files.
