HarmonyOS鸿蒙Next中使用ohaudio native播放音频卡顿

HarmonyOS鸿蒙Next中使用ohaudio native播放音频卡顿 我使用ohaudio native播放单声道采样为8000的单声道音频pcm，声音不正常，一卡一卡的，能否给个数据写入例子看看，或者播放音频的native例子。

#include "Audio.h"
#include "ppcs/AVData.h"
#include <unistd.h>
#include "hilog/log.h"
#undef LOG_TAG
#define LOG_TAG "QN_Audio"

int32_t writeAudioData(OH_AudioRenderer* renderer, void* context, void* buffer, int32_t length){
  Audio* pAudio = (Audio*)context;
  AVData aVData;
  if (pAudio->pQueue->Pop(aVData)) {
    memcpy(buffer, aVData.frameBuffer, aVData.size);
    length = aVData.size;
    // free(aVData.frameBuffer);
    OH_LOG_INFO(LOG_APP, "这里播放音频length:%{public}d", length);
  }
  return 0;
}

int32_t onError(OH_AudioRenderer* renderer, void* context, OH_AudioStream_Result error){
  return 0;
}

Audio::Audio(){
  pQueue = new SafeQueue();
  OH_AudioStreamBuilder_Create(&pBuilder, AUDIOSTREAM_TYPE_RENDERER);
  OH_AudioStreamBuilder_SetSamplingRate(pBuilder, 8000);
  OH_AudioStreamBuilder_SetChannelCount(pBuilder, 1);
  OH_AudioStreamBuilder_SetSampleFormat(pBuilder, AUDIOSTREAM_SAMPLE_S16LE);
  OH_AudioStreamBuilder_SetEncodingType(pBuilder, AUDIOSTREAM_ENCODING_TYPE_RAW);
  OH_AudioStreamBuilder_SetRendererInfo(pBuilder, AUDIOSTREAM_USAGE_GAME);
  callBacks.OH_AudioRenderer_OnWriteData = writeAudioData;
  callBacks.OH_AudioRenderer_OnStreamEvent = nullptr;
  callBacks.OH_AudioRenderer_OnInterruptEvent = nullptr;
  callBacks.OH_AudioRenderer_OnError = onError;
  OH_AudioStreamBuilder_SetRendererCallback(pBuilder, callBacks, this);
  OH_AudioStreamBuilder_SetLatencyMode(pBuilder, AUDIOSTREAM_LATENCY_MODE_FAST);
  OH_AudioStreamBuilder_GenerateRenderer(pBuilder, &pAudioRenderer);
}

Audio::~Audio(){
  if(pBuilder){
    OH_AudioStreamBuilder_Destroy(pBuilder);
    pBuilder = nullptr;
  }
  if(pAudioRenderer){
    OH_AudioRenderer_Release(pAudioRenderer);
    pAudioRenderer = nullptr;
  }
}

void Audio::playSound(){
  OH_AudioRenderer_Start(pAudioRenderer);
}
