New Revision: 241375
URL: http://svn.freebsd.org/changeset/base/241375

Log:
  Cast vendor-specific spell on VIA VT1818S codecs alike to VT1708S to
  make analog input loopback and dual-stream playback work by enabling
  signal mixing by nid 22, as it should be according to info returned by
  the CODEC.  Otherwise pin nid 28 receives only signal from DAC nid 16.
