I have a sound output problem whenever I play files in Rhythmbox, and it's the same in Banshee. Basically, although the files play fine, if I want to fast forward I get this annoying squeaky sound, in other words the transition is not smooth. Strangely enough, if I play the same files in VLC and I fast forward, I don't get that behavior and the transition is very smooth. Is it a codec issue? How can this be fixed? Any ideas anyone?
