关于ＤＸ播放音效的问题

xwq

我在用IDirectMusicLoader8，IDirectMusicPerformance8创建的接口，过程如下
        CoCreateInstance(CLSID_DirectMusicLoader, NULL, CLSCTX_INPROC,
                IID_IDirectMusicLoader8, (void**)&m_pLoader);     
        CoCreateInstance(CLSID_DirectMusicPerformance, NULL, CLSCTX_INPROC,
                IID_IDirectMusicPerformance8, (void**)&m_pPerformance );
        m_pPerformance->InitAudio( NULL, NULL, m_hWnd, /*DMUS_APATH_DYNAMIC_STEREO*/DMUS_APATH_SHARED_STEREOPLUSREVERB, 64, DMUS_AUDIOF_ALL,        NULL );


在程序运行时输出窗口一直提出以下警告：
DMIME: Couldn't find SegState in GetParam call.
DMIME: Couldn't find SegState in GetParam call.
DMIME: Couldn't find SegState in GetParam call.
DMIME: Couldn't find SegState in GetParam call.
DMIME: Couldn't find SegState in GetParam call.
DMIME: Couldn't find SegState in GetParam call.
请问高手这怎么解决？
