Yeelight bulb 1s color noise problem after update

After updating my lamps to latest update 2.1.7_0037 - after switching them on i now hear a little noise simmilar to ultrasound and it’s annoying. Lamps which is still have not updated is fine.

Model: yeelink.light.color4

I’m only one with such problem?
Also there is no way do downgrade or rollback firmware?
