  SVN rev 222826 on 2011-06-07 17:01:52Z by mav
  
  Make automatic hw.snd.default_unit choice a bit more intelligent. Instead
  of just setting it to the first registered device, reevaluate it for each
  device registered, trying to choose best candidate, unless one was forced.
  For now use such preference order: play&rec, play, rec.
  
  As side effect, this should workaround the situation when HDMI audio output
  of the video card, usually not connected to anything, becomes default, that
  requires manual user intervention to make sound working. If at some point
  this won't be enough, we can try to fetch some additional priority flags
  from the device driver.
