Comment:

 The same here on Ubuntu Jaunty. Especially Ekiga and gnome-sound-recorder
 are completely unusable (I'd like to ditch Skype, thanks)!

 However, I can record something using directly:

 gst-launch pulsesrc ! vorbisenc ! oggmux ! filesink location="me.oga"

 It's passably clear (low quality microphone, anyway). The strange thing
 is, sometimes it does record me correctly, sometimes (especially if it's
 the first time you run this command) it gives me a lot of errors like:

 WARNING: from element /GstPipeline:pipeline0/GstPulseSrc:pulsesrc0: Can't
 record audio at an adequate rate
 Additional debug info:
 gstbaseaudiosrc.c(805): gst_base_audio_src_create ():
 /GstPipeline:pipeline0/GstPulseSrc:pulsesrc0:
 dropped 2205 samples

 After 8-10 minutes of recording it hangs, though.
