HarmonyOS 鸿蒙Next 在使用AVPlayer时传入本地的MP3文件播放没有声音

参考demo：

import { media } from '@kit.MediaKit';
import { common } from '@kit.AbilityKit';
[@Entry](/user/Entry)
[@Component](/user/Component)
struct Index {
  [@State](/user/State) message: string = 'Hello World';
  build() {
    Column() {
      Button('播放')
        .onClick(async () => {
         await new AVPlayerDemo().avPlayerFdSrcDemo()
        })
    }
    .justifyContent(FlexAlign.Center)
    .height('100%')
    .width('100%')
  }
}
export class AVPlayerDemo {
  setAVPlayerCallback(avPlayer: media.AVPlayer) {
    // 状态机变化回调函数
    avPlayer.on('stateChange', async (state: string) => {
      switch (state) {
        case 'initialized':
          avPlayer.prepare()
          break;
        case 'prepared':
          avPlayer.play()
          break;
        case 'completed':
          avPlayer.stop()
          break
      }
    })
  }
  async avPlayerFdSrcDemo() {
    let avPlayer: media.AVPlayer = await media.createAVPlayer()
    let context = getContext(this) as common.UIAbilityContext
    let fileDescriptor = await context.resourceManager.getRawFd('noguess.mp3')
    let avFileDescriptor: media.AVFileDescriptor =
      { fd: fileDescriptor.fd, offset: fileDescriptor.offset, length: fileDescriptor.length }
    this.setAVPlayerCallback(avPlayer)
    avPlayer.fdSrc = avFileDescriptor
  }
}
