好吧，我不得不承认这是个蠢问题

hmhm

LPDIRECTSOUNDNOTIFY8 lpDsNotify;
DSBPOSITIONNOTIFY PositionNotify[2];

hr = m_pDSBuffer->QueryInterface(IID_IDirectSoundNotify8,(LPVOID*)&lpDsNotify);

pos1 = PositionNotify[0].dwOffset = desc.dwBufferBytes / 2;
PositionNotify[0].hEventNotify = handle[0];

pos2 = PositionNotify[1].dwOffset = desc.dwBufferBytes;
PositionNotify[1].hEventNotify = handle[0];
               
hr = lpDsNotify->SetNotificationPositions(2, PositionNotify);

hr = lpDsNotify->SetNotificationPositions(2, PositionNotify);这里2改为1就不会出错，如果是2的话就会返回错误DSERR_INVALIDPARAM 。谁来告诉我哪里做错了?

应该是1和0吧！2的话叫做数组下标越界
