Yes. Some smartass tought that giving realtime privileges to PulseAudio on the fly will make sound better. And it do, but RT have one small glitch that's render it no good for desktops - if something goes RT then all other's going to hell.
So, we have RT PulseAudio that palys as smooth as it never did and choppy video playback with 5% CPU usage
(with 2.6.32 kernel because they forgot to patch 2.6.31 kernel so beware of Ubuntu users complaining about it when Lucid arrive)
