Ubuntu :: Rhythmbox Keeps Playing Songs With No Sound?

For some reason, Rhythmbox will show itself playing a song (the notification in the top right corner) but I hear no sound. I can go to the application itself and see the play slider moving. I can't pause it or anything. if it's a bug in Rhythmbox itself. If I browse to the directory, and right click > Open with Rhythmbox, it works perfectly (although I still can't pause it)

Also, if I jump to another song, and then play the song it was playing silently, it works. Not sure why it does this.

I doubt it's the files themselves because I've been downloading all my songs from one site, and never had an issue in iTunes on a windows PC. It only does this to about 3 songs out of 164. It used to do this to only 2, but now it's doing it to 3 since the past few days when adding more songs.
