Same problem here with maverick and hp2133. Using recording application like gnome-sound-recorder or skype pulseaudio process eats all available cpu time (cpu usage 100%) and the sound is stuttering. tsched=0 helps a bit (pulseaudio not taking all available cpu), but pulseaudio eats still 30% of cpu time. Aplay and arecord works fine.
