Sound in Linux (and pulseaudio) – finally works with rt-kernel?

Just wanted to share an interesting observation. I had quite some trouble with some programs in Linux playing sound (most programs like vnc working nicely), mainly with kvm but also musescore - it was allways stuttering. For fun I just installed the 3.0.0-2-rt-amd64 kernel and hey, the stuttering is gone!

Will continue to monitor this. Not sure what I lost using the realtime kernel.
