I'd call it stuttering rather than crackling, but I'm getting similar on a fresh Jaunty install.
for each stutter, pulseaudio debug gives: I: module-alsa-sink.c: Underrun! D: protocol-native.c: Requesting rewind due to end of underrun. Fiddling with the settings in /etc/pulse/daemon.conf has not been successful. I've tried various number for default-fragments and default-fragment-size-msec. I've tried setting high-priority = yes, realtime-scheduling = yes, and resample-method = trivial (and others) I still get underruns (which sounds like stutters) when I'm changing windows, scrolling, etc., particularly if I'm running something even slightly CPU intensive (such as montage).
