About AAC decoder config

Hi all,

I have developed a MKV media source, it's ok to play video, but audio is not, and i have check aduio parameter, it's correct. This is my config and file info:

WAVEFORMATEX afmt;
WAVEFORMATEX* wfe = &afmt;
ZeroMemory(wfe, sizeof(WAVEFORMATEX));
wfe->nChannels = Channels;
wfe->nSamplesPerSec = SamplingFrequency;
wfe->wBitsPerSample = BitDepth;
wfe->wBitsPerSample = wfe->wBitsPerSample==0?16:wfe->wBitsPerSample;
wfe->nBlockAlign = (WORD)((wfe->nChannels * wfe->wBitsPerSample) / 8);
wfe->nAvgBytesPerSec = wfe->nSamplesPerSec * wfe->nBlockAlign;

int size = sizeof(HEAACWAVEINFO) + CodecPrivate.GetCount();
HEAACWAVEINFO* pWaveInfo = (HEAACWAVEINFO*)malloc(size);
memset(pWaveInfo, 0, size);
memcpy(&(pWaveInfo->wfx), wfe, sizeof(WAVEFORMATEX));

pWaveInfo->wAudioProfileLevelIndication = 0xfe;
pWaveInfo->wPayloadType = 0;//raw aac
pWaveInfo->wStructType = 0;

pWaveInfo->wfx.cbSize = size- sizeof(WAVEFORMATEX);

if(CodecPrivate.GetCount() > 0)
	memcpy((BYTE*)(pWaveInfo + 1),CodecPrivate.GetData(), CodecPrivate.GetCount());

HRESULT hr = MFCreateMediaType(&pType);
if (SUCCEEDED(hr))
{
	hr = pType->SetGUID(MF_MT_MAJOR_TYPE, MFMediaType_Audio);
}

hr = MFInitMediaTypeFromWaveFormatEx(pType, (const WAVEFORMATEX*)pWaveInfo, size);
hr = pType->SetGUID(MF_MT_SUBTYPE, MFAudioFormat_AAC);

free(pWaveInfo);
pWaveInfo = NULL;
