I, too, am recently having difficulty with there being no sound on Windows Media Player. I decided to erase my RealPlayer because I prefer WMP. I used to have no issues, about two months ago. This weekend after trying to download some songs I can't hear sound on WMP but it is playing. The big difference is that the files are 18-22 minutes in length for a normal song. I can't figure out what I've done either. I've never had problems with fake MP3 files. Can anyone help us out? Thank you.
