Is this the same question as in the MFC area? In that case it is clear what is wrong. BSTR is a special type of string that is preceded by a length (before the first character in the string). There are special functions to create and destroy such strings. Using MFC, the most easy way is to use a CString, like this:

CString strFileName = _T("C:\\fire.wav");
BSTR bstrFileName = strFileName.AllocSysString();

m_red.PlayWav(&bstrFileName);

::SysFreeString(bstrFileName);

Regards,
Stefan
