Error 80040241

Hi ,
i have a PCM file which my application converts to WAV file.
This file when streaming through an ASP page does not play in windows media
player 9 + series ( error : The source filter for this file could not be
loaded).
WMP 7 and Winamp supports and plays this file. when i save this file n then
play on WMP 9 series it plays. Can someone please help me resolve this issue.
