I have a shared media folder that I have all of my mp3's in. When I try to play them using Ubuntu, I get no sound, but the media player (Rhythmbox, Exaile, etc) display that they are playing the file, it looks like everything is playing but no sound. I have checked and rechecked the volume levels of the system and each application and I see no issues.

If I move a file to the local drive, it plays just fine.

I do sound checks while the file is playing and I get audio (front left, front right) from the test but not from the media file that I am playing. Any help would be greatly appreciated.
