Title:
  No signal from external mic on MacBookPro

Status in “gnome-media” package in Ubuntu:
  Expired

Bug description:
  Binary package hint: gnome-media

  The external mic provides no input signal. gnome-volume-control shows the input channels "internal microphone", "analog line-in", "rear microphone" and "analog microphone". None of these pick up anything from the external microphone. 
  "Hardware" is set to "Analog stereo duplex", but I also tried "Analog Surround 4.0 + Analog Stereo Input" without success. 

  Internal mic works (verified with gnome-volume-control and gtk-recordMyDesktop).
  External microphone hardware was verified with another computer.

  Natty (dev. branch) on a MacBookPro6.2

  lspci identifies the sound card as:
