[quote]if MP3 and WAV are playing, then there is likely nothing wrong with your code and you have found a problem with WMA file reader (which is fairly new to NAudio and hasn't been extensively tested yet). If you are able to step into NAudio code then you could see what the WMAFileReader.Read method is doing

Thanks for the reply Mark. I really don't have have the time to figure it out... But I think will will simply just drop support for WMA in my app for now. WAV, MP3 are really the only formats I need. Thanks for your time.
