I am having a strange audio issue that I couldn't find an answer to with the search function. I am attempting to stream files with WIndows Vista and VLC. The file begins to play and the audio track is working but not very well. The problem is the vocal track is usually muffled but the other sounds come through fine. For example I tried watching Batman The Dark Knight returns part 1 and the race at the beginning the cars and the crowd come through clearly but when Bruce starts talking I can't hardly hear it. If their is no other background audio when someone is talking consistently the audio will get loud then muffled than loud again. The only thing I could figure is the audio is not buffering properly.
