How to use the pigpio.configureClock function in pigpio

function initialise(red, green, blue) {
		if (red && green && blue) {
			pigpio.configureClock(10, pigpio.CLOCK_PWM); // Configures PiGPIO to use PWM as clock source (by default it uses PCM which conflicts with BeoCreate 4-Channel Amplifier).
			pigpio.initialize(); // pigpio C library initialized here
			
			ledR = new pigpio.Gpio(red, {mode: pigpio.Gpio.OUTPUT});
			ledG = new pigpio.Gpio(green, {mode: pigpio.Gpio.OUTPUT});
			ledB = new pigpio.Gpio(blue, {mode: pigpio.Gpio.OUTPUT});
			ledInitialised = true;
			beoBus.emit("general", {header: "requestShutdownTime", content: {extension: "led"}});
			return true;
		} else {
			return false;
		}
	}

module.exports.create = function(ws, uiConfig) {
  // Tells the underlying gpio library to use the
  // PWM pin as a clock source, rather than the PCM
  // pin that provides I2S audio to DACs
  pigpio.configureClock(5 /* pigpio's default duty cycle */, pigpio.CLOCK_PWM);

  const io = new IO({
    enableSoftPwm: true,
    // Only enable pins used in the config
    // to avoid clashing with other components
    includePins: collectPinNumbers(uiConfig)
  });

  var board = new five.Board({
    io: io,
    repl: false
  });
