Hw5 controller high frequency sound problem

Hi

I installed and configured an HW5 RGB controller
on an RGB LED BAR DC 12V, but the high frequency sound is too loud. It’s a lot when you adjust the brightness and not at the maximum brightness, but it’s very loud at 30% to 90% brightness. Is there a solution?

Ps Control is done with the FUT089 remote control

We already suggested your side to set frequency at 250HZ
