Since kde 4.2 came out I've been using kubuntu (again, switched to gnome about 18 months back) and there are no recording problemens here, it all basically works out of the box, even though pulseaudio is still installed because it's somehow needed to get sound working with flash movies in firefox.
The problem might therefore not even be pulseaudio, but the interaction between the gnome volume manager and pulseaudio.
Hope this somehow helps pinpoint the problem.
