svn commit: r242357 - head/sys/dev/sound/pci/hda

[Alexander Motin]

Author: mav
Date: Tue Oct 30 12:44:30 2012
New Revision: 242357
URL: http://svn.freebsd.org/changeset/base/242357

Log:
  Set all pins initial connection status to unknown (2) and then update it
  with the real value in regular way if sensing is supported.  This fixes
  minor inconsistency when playback redirection appeared in undefined state
  on boot if headphones were not connected.
