Yeelight YLXD39YL not working properly

My Yeelight smart LED ceiling light makes buzzing noices and flickers when I switch it to Sunrise or any other mode. It only works properly at 4000K, at warmer or cooler temperatures it also flickers and makes noises. Firmware is up to date and I tried to reset it multiple times but without any success.
Does anybody has any idea what could be wrong with it?
