我的Angular应用程序没有检测到我的耳机扬声器(使用enumerateDevices)

import { Component } from '@angular/core';

declare var navigator: any;

detectSpeakers() {
  if (navigator.mediaDevices && navigator.mediaDevices.enumerateDevices) {
    navigator.mediaDevices.enumerateDevices()
      .then(devices => {
        devices.forEach(device => {
          if (device.kind === 'audiooutput') {
            console.log('Speaker detected:', device.label);
          }
        });
      })
      .catch(error => {
        console.error('Error detecting speakers:', error);
      });
  } else {
    console.error('enumerateDevices not supported');
  }
}

<button (click)="detectSpeakers()">Detect Speakers</button>
