looks like buzzer has a separate input, so it acts like two separate boards, ws2812b LED board and buzzer board.

I couldn't tell right off what the buzzer input wants.  Probably a TTL on/off or maybe a servo signal that buzzes above 1500us.

For this buzzer you need a buffered output like here:

Or similar as the one used in Naze32:
