Also, note that on some AC'97 systems, you need an inv_eapd quirk. Please verify by muting the following mixer controls (using alsamixer in a Terminal):

Simple mixer control 'Headphone Jack Sense',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]
^^^^^^^^^^^^^^^^^^^^^^^

Simple mixer control 'Line Jack Sense',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]
^^^^^^^^^^^^^^^^^^^^^^^

Simple mixer control 'External Amplifier',0
  Capabilities: pswitch pswitch-joined
  Playback channels: Mono
  Mono: Playback [on]
^^^^^^^^^^^^^^^^^^^^^^^
