SYMPTOMS
When you create applications that modify or create attributes in Windows Media Audio (WMA) files using the IWMAudioInfo API, information in the file header may become corrupt, causing the stream to be unplayable.



CAUSE
The file size may be stored incorrectly, in a way that does not match the actual size of the file. As a result, the audio file does not play.



RESOLUTION
Microsoft has confirmed that this is a problem in Microsoft Windows Media SDK version 4.0.



WORKAROUND
To work around this issue, run the ASFCHECK tool against the file to reset the file header with the proper information.



MORE INFORMATION
Custom applications that may use the IWMAudioInfo API are used for adding special attributes to Windows Media Audio (WMA) files. Examples of these attributes are Artist, Title, Album, Year, Comments, and so on.
