New Revision: 243062
URL: http://svnweb.freebsd.org/changeset/base/243062

Log:
  MFC r242357:
  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.
