I do experience this bug even using _Alsa_ as output. It is less noticeable, but it still occurs, especially on my not-so-recent computer (1.2 GHz Athlon, 1.25 GB Ram), which anyway is good at playing any media under Gutsy.
So I suppose this is not a pulseaudio bug: pulseaudio is just using more CPU, and that's why the bug is more noticeable.
