Soy un principiante cuando se trata de electrónica. Así que quiero reproducir sonidos con mi controlador y estoy usando un WT020-SD-16P

pero cuando lo cargué sin errores, intenté presionar el interruptor de reproducción / pausa conectado al pin 9 del módulo. Cuando intenté presionar los interruptores no hay salida de audio. Estoy usando un altavoz de 8ohm. ¿Hice algo mal? Pero seguí todas las instrucciones en los foros. por favor ayúdame.
