Windows 8 XAudio2和*.wav加载，HRESULT 0x88960001

我正在尝试加载一个*.wav文件，该文件是microsoft wav/8位pcm文件。我正在使用以下代码加载数据：

class WavFile : public AudioSource, public LoadableObject
{
public:
    WavFile( void )
        : AudioSource()
        , LoadableObject()
    { }

    virtual concurrency::task<void> Load( Platform::String^ path )
    {
        buffer = nullptr;

        BasicReaderWriter^ rw = ref new BasicReaderWriter();
        return rw->ReadDataAsync( path ).then([this, path]( const Platform::Array<byte>^ arr ){

            DWORD chunkId = 0, fileSize = 0, chunkSize = 0, extra = 0;

            ByteStream stream( arr );

            stream.ReadData( &chunkId, sizeof( chunkId ) );
            //chunkId = stream.ReadDWORD();
            char test[4];
            for(unsigned int i=0; i <4; i++)
                test[i] = ((char *)&chunkId)[i];
            if ( chunkId != 'FFIR' ) throw ref new Platform::FailureException( L"Could not get RIFF chunk in file " + path + L", chunkId=" + chunkId.ToString() );

            fileSize = stream.ReadDWORD();
            if ( fileSize <= 16 ) throw ref new Platform::FailureException( L"Wave file size is too small; " + path );

            extra = stream.ReadDWORD();
            for(unsigned int i=0; i <4; i++)
                test[i] = ((char *)&extra)[i];
            if ( extra != 'EVAW' ) throw ref new Platform::FailureException( L"Could not get WAVE chunk in file " + path + L", chunkId=" + chunkId.ToString() );

            bool formatChunk = false;
            for(unsigned int i = 12; i < fileSize; )
            {
                stream.Seek( i, true );
                chunkId = stream.ReadDWORD();
                stream.Seek( i + 4, true );
                chunkSize = stream.ReadDWORD();
                if ( chunkId = ' tmf' )
                {
                    stream.Seek( i + 8, true );
                    stream.ReadData( &waveFormat, sizeof( WAVEFORMATEX ) );
                    formatChunk = true;
                    break;
                }

                chunkSize += 8 + 1;
                chunkSize &= 0xfffffffe;
                stream.Seek( chunkSize, false );
                i += chunkSize;
            }
            if ( !formatChunk ) throw ref new Platform::FailureException( L"Could not get fmt chunk in file " + path );

            bool filledData = false;
            for(unsigned int j=12; j < fileSize; )
            {
                stream.Seek( j, true );
                chunkId = stream.ReadDWORD();
                for(unsigned int i=0; i <4; i++)
                    test[i] = ((char *)&chunkId)[i];
                stream.Seek( j + 4, true );
                chunkSize = stream.ReadDWORD();
                if ( chunkId == 'atad' )
                {
                    byte *bufferData = new byte[chunkSize];
                    stream.Seek( j + 8, true );
                    stream.ReadData( bufferData, chunkSize );
                    buffer = ref new Platform::Array<byte>( bufferData, (unsigned int)chunkSize );
                    delete bufferData;

                    xbuffer.AudioBytes = chunkSize;
                    xbuffer.pAudioData = buffer->Data;
                    xbuffer.PlayBegin = 0;
                    xbuffer.PlayLength = 0;

                    filledData = true;
                    break;
                }
                chunkSize += 8 + 1;
                chunkSize &= 0xfffffffe;
                j += chunkSize;
            }
            if ( !filledData ) throw ref new Platform::FailureException( L"Could not find data chunk in file " + path );

        });
    }
};

我在多个地方读到，这个HRESULT是某种Windows8错误，已经一年多没有修复了。我不能接受这是一个持续的bug，更倾向于认为这是我的代码的问题。您可以签出。

将XAudio2SourceVoice*的发送列表设置为空时，IXAudio2接口必须至少设置了一个主控语音。

这是XAUDIO2\u E\u无效的调用，它与您传递的参数值不同。啊，所以我没有首先创建主控语音，这显然需要设置到位。我很惊讶没有更好的HRESULT值来描述这种情况。

AudioManager::AudioManager(void)
{
    instance_count++;
    if ( instance == nullptr )
    {
        DX::ThrowIfFailed( XAudio2Create( &instance, 0 ) );
    }
}


AudioManager::~AudioManager(void)
{
    /* Remove all the voices that were added in this audio manager */

    instance_count--;
    if ( instance_count == 0 )
    {
        HaltAudio();
        instance->Release();
        instance = nullptr;
    }
}
