Recently I've noticed a high pitched whine coming from my Drop CTRL if I have the LEDs turned on at all. It's quiet but clearly noticeable and is driving me crazy.
I had assumed it was a USB issue so I tried both ports on the CTRL but no change. I tried different ports on my PC but no change. I was using a Custom cable so went and tried the USB cable that came with the keyboard but the whine was still there. Anyone else have this issue?
