javascript - 通过统一使用电路调用remoteAudioUrl的问题

Question

如果可以的话，我们不能早点听会议。

使用的代码片段是这个

client.addEventListener('callStatus', evt => {
  if (!call || call.callId === evt.call.callId) {
    output(`callStatus event received. reason: ${evt.reason}, state: ${evt.call.state}`);
    call = evt.call;
    convList.disabled = !call.isRemote && call.isEstablished;
    enableVideo.disabled = !(!call.isRemote && call.isEstablished);
    enableScreenShare.disabled = !(!call.isRemote && call.isEstablished);
    enableRecording.disabled = !(!call.isRemote && call.isEstablished);
    // Set local video stream
    localVideo.src = call.localVideoUrl || '';
    // Enable video checkbox
    if (call.isEstablished) {
      //remoteAudio.src = call.remoteAudioUrl.substring(5);
      remoteAudio.src = call.remoteAudioUrl;
      // Set remote video streams (up to two in this example)
      if (call.participants && call.participants.length > 0) {
        remoteVideo1.src = call.participants[0].videoUrl;
      }
      if (call.participants && call.participants.length > 1) {
        remoteVideo2.src = call.participants[1].videoUrl;
      }
    } else {
      remoteAudio.src = '';
      remoteVideo1.src = '';
      remoteVideo2.src = '';
    }
  }
});

我们需要知道上个月是否发生了变化，因为它以前有效
