i have connected buzzer to D8 pin of the arduino nano and uncommented #define BUZZER and #define D8BUZZER in the config.h file. My buzzer beeps at very low sound which is not audible also.
Please help me as soon as possible

The I/O pins is not enough to power the buzzer fully.
You can use a transistor to drive the buzzer.
