See files in attached tarball. Contents are:
* system boot (docked)
  => alsa-info.txt_3[34]_docked
* undock
  => alsa-info.txt_3[34]_undocked
* suspend - dock (while suspended) - resume
  => alsa-info.txt_3[34]_after_resume_docked
* undock - redock (this disables the internal speakers)
  => alsa-info.txt_34_after_resume_redocked
