New Revision: 184230
URL: http://svn.freebsd.org/changeset/base/184230

Log:
  Add some special handeling for AD1981HD codec. It has very unusual design
  with several points unappropriate for the present parser. This patch
  disables input-to-output analog monitoring but instead fixes recording.
  
  Tested by Tobias Grosser on ThinkPad T61p.
