      enableVoiceEarMonitor:
      - (void)enableVoiceEarMonitor:
      (BOOL)enable

      Enabling in-ear monitoring

      After enabling in-ear monitoring, anchors can hear in earphones their own voice captured by the mic. This is designed for singing scenarios.
      
      In-ear monitoring cannot be enabled for Bluetooth earphones. This is because Bluetooth earphones have high latency. Please ask anchors to use wired earphones via a UI reminder.
      Given that not all phones deliver excellent in-ear monitoring effects, we have blocked this feature on some phones.
      Param
      DESC
      enable
      YES: enable; NO : disable
      Note
      In-ear monitoring can be enabled only when earphones are used. Please remind anchors to use wired earphones.

      The information, including playback ID, file path, and loop times, is passed in the startPlayMusic API.
      1. If you play the same music track multiple times, please use the same ID instead of a separate ID for each playback.
      2. If you want to play different music tracks at the same time, use different IDs for them.
      3. If you use the same ID to play a music track different from the current one, the SDK will stop the current one before playing the new one.
