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.
