HarmonyOS鸿蒙Next中模拟器总是卡在获取录音位置，这是为啥？

async start(callback: (state: number, data?: ArrayBuffer) => void) {
  let stateGroup = [audio.AudioState.STATE_PREPARED, audio.AudioState.STATE_PAUSED, audio.AudioState.STATE_STOPPED]
  if (stateGroup.indexOf(this.audioCapturer.state) === -1) {
    console.error('启动录音失败')
    callback(audio.AudioState.STATE_INVALID)
    return
  }
  await this.audioCapturer.start()
  this.isRecording = true
  let bufferSize: number = await this.audioCapturer.getBufferSize();

  while (this.isRecording) {
    let buffer = await this.audioCapturer.read(bufferSize, true)
    console.info('录音大小：' + buffer.length)
    if (buffer === undefined) {
      console.error('读取录音数据失败')
    } else {
      callback(audio.AudioState.STATE_RUNNING, buffer)
    }
  }
  callback(audio.AudioState.STATE_STOPPED)
}

使用模拟器录音时，总是这行代码：

模拟器有问题用真机试试

真机也是一样，

有一点猜测。卡着是不是因为读取操作是放到最后执行的？即录音结束才执行的读取。推测是缓存区内容太多。

我的这样的操作也是卡死。参照指南文档将记录操作改成录制过程中循环读取、保存。我这样成功了，不知道是不是这样
