I received and Ender 5 pro and BLTouch for Christmas.  I have it ready and right off, noticed that the firmware installed did not recognize the BLTouch.  I downloaded the latest firmware and installed it, but now I have a loud hum coming from the LCD.

 

The firmware was 4.2.2 for BLTouch, Aug 29, 2020.

Thanks,

Kent

For those that have read elsewhere about back leveling your firmware, I found that what I believe to be the original Creality site, www.creality.com/download and found the following firmware update.

4.2.2 Ender-5 pro 32bit Marlin2.0.1 BLtouch V1.1.1without adapter board.rar

That fixed many of my issues including the loud buzz.
