I have the Holybro Kakute F4 AIO Flight Controller and I'm having issues with the buzzer feature. I have a buzzer that when provided 5v from a power supply it buzzes as expected. However after soldering to the BUZ pads on the Kakute FC the buzzer simply clicks when activated. I've setup my Flysky FS-i6 switch to use AUX1 to activate the buzzer. This works fine. However when activated the buzzer only clicks instead of beeping. Is there something wrong with the board? Or did I miss a step?
