[Bug 536858] Re: USB-Audio devices do not show up as input devices

2.6.32-15.22-generic works fine. This is kind of severe for me, since
the built-in analog mic input does not work in Ubuntu.

For comparison I will rerun apport-collect using this kernel.

** Package changed: linux (Ubuntu) => alsa-driver (Ubuntu)

** Tags added: apport-collected

** Description changed:

  This is a webcam microphone, it shows up in the "Hardware" tab of Sound
  Preferences (and in "Configuration of pavucontrol) but not in the
  "Input" tab (or "Input Devices" in pavucontrol).
  
  This is a regression since possibly a week or two.
