Plugging almost any headset into the front headset jacks on my machine results in noise in the headphones as well as in Skype conversations and/or recording. Said noise is, however not head in the regular speakers (except when playing back recordings, of course.

Are you sure that it is noise ?
Just test Ubuntu 11.04 Live CD
HP has no sound when select Analog Headphone connector in gnome sound preference and HP has sound when select Analog Output as connector
I guess PA server cannot find "Headphone Playback Volume". since only "Headphone Playback Switch" exist in Ubuntu 11.04
The other strange thing is alsamixer can mute but unmute has no effect ,need to use gnome sound preference
