HarmonyOS 鸿蒙Next avPlayer是否播放完后自动销毁 不执行reset()或release()方法无效

页面中要播放4个mp3,点击第一个按钮播放第1个mp3,播放完第1个后，再点击第二个按钮去播放第2个mp3，但是第二个按钮点一次无效，必须要点第二次才会播放，请问是什么原因呢？

日志里面提示：PipeLineThread HiPlayer_8_A remove all Task

我已在代码里控制第一个音频播放完之后不去执行stop()方法，同样无效，以下是代码片段

initAvPlayer() {
  media.createAVPlayer().then((avPlayer: media.AVPlayer) => {
    this.avPlayer = avPlayer;
    this.playerCallback(this.avPlayer);
   })
}

playerCallback(avPlayer: media.AVPlayer) {
  //this.avPlayer?.stop()
  avPlayer.on(‘timeUpdate’, (time: number) => {
    //console.info('AVPlayer timeUpdate. time = ’ + time / 1000);
  })
  // error回调监听函数,当avPlayer在操作过程中出现错误时调用 reset接口触发重置流程
  avPlayer.on(‘error’, (err: BusinessError) => {
    console.error(Invoke avPlayer failed, code is ${err.code}, message is ${err.message});
    avPlayer.reset(); // 调用reset重置资源，触发idle状态
  })
  // 状态机变化回调函数
  avPlayer.on(‘stateChange’, async (state: string, reason: media.StateChangeReason) => {
    switch (state) {
      case ‘idle’: // 成功调用reset接口后触发该状态机上报
        console.info(‘AVPlayer state idle called.’);
        if(this.needPlayAnswer && this.avPlayer!=undefined){
          this.needPlayAnswer=false
          this.avPlayer.url=this.questionList[this.currentIndex].answermp3
        }

        break;
      case ‘initialized’: // avplayer 设置播放源后触发该状态上报
        console.info(‘AVPlayer state initialized called.’);

        avPlayer.audioRendererInfo = {
          usage: audio.StreamUsage.STREAM_USAGE_MUSIC,
          rendererFlags: 0
        }
        avPlayer.prepare();
        break;
      case ‘prepared’: // prepare调用成功后上报该状态机
        console.info(‘AVPlayer state prepared called.’);
        avPlayer.play()
        break;
      case ‘completed’: // prepare调用成功后上报该状态机
        console.info(‘AVPlayer state completed called.’);

        if(this.playAnswer){
          this.needPlayAnswer=true
          this.playAnswer=false
          this.avPlayer?.reset()
        }
        else{
          this.avPlayer?.seek(0)
          this.avPlayer?.pause()
        }
        break;
      case ‘playing’: // play成功调用后触发该状态机上报
        console.info(‘AVPlayer state playing called.’);
        break;
      case ‘paused’: // pause成功调用后触发该状态机上报
        console.info(‘AVPlayer state paused called.’);
        break;
      case ‘stopped’: // stop接口成功调用后触发该状态机上报
        console.info(‘AVPlayer state stopped called.’);
        //avPlayer.reset()
        break;
      case ‘released’:
        console.info(‘AVPlayer state released called.’);
        break;
      default:
        console.info(‘AVPlayer state unknown called.’);
        break;
    }
  })
}
