      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

      true: enable; false : disable
      Note
      In-ear monitoring can be enabled only when earphones are used. Please remind anchors to use wired earphones.
