Greets!

Just to verify that Alexander isn't crazy, I too am having a very similar 
issue with smart_crossfade.  I'm using a modified version of the RadioPi 
example from the liquidsoap documents.  It worked great in 1.0.1, but now 
does nothing (no logs either) in the latest 1.1.1 from git (compiled on 
Ubuntu 13.04, amd64).

Here's my code:
------------------------------------------------------------
# Tweaked custom crossfade to deal with jingles..
def josh_crossfade (~start_next=5.,~fade_in=3.,~fade_out=3.,
                     ~default=(fun (a,b) -> sequence([a, b])),
                     ~high=-15., ~medium=-32., ~margin=4.,
                     ~width=2.,~conservative=false,s)
  fade.out = fade.out(type="sin",duration=fade_out)
  fade.in  = fade.in(type="sin",duration=fade_in)
  add = fun (a,b) -> add(normalize=false,[b, a])
  log = log(label="smart_crossfade")

  def transition(a,b,ma,mb,sa,sb)

    list.iter(fun(x)-> log(level=4,"Before: #{x}"),ma)
    list.iter(fun(x)-> log(level=4,"After : #{x}"),mb)

    if ma["type"] == "J" or mb["type"] == "J" then
      log("Old or new file is a jingle: sequenced transition.")
      sequence([sa, sb])
    elsif
      # Do not fade if it's already very low.
      b >= a + margin and a <= medium and b <= high
    then
      log("new >= old + margin, old <= medium and new <= high.")
      log("Do not fade if it's already very low.")
      log("Transition: crossed, no fade.")
      add(sa,sb)

    # What to do with a loud end and a quiet beginning ?
    # A good idea is to use a jingle to separate the two tracks,
    # but that's another story.

    else
      # Otherwise, A and B are just too loud to overlap nicely,
      # or the difference between them is too large and overlapping would
      # completely mask one of them.
      # log("No transition: using default.")
      # default(sa, sb)
      log("Transition: crossed, fade-in, fade-out.")
      add(fade.out(sa),fade.in(sb))
    end
  end

  smart_cross(width=width, duration=start_next, conservative=conservative,
              transition,s)
end
------------------------------------------------------------

Not certain if it helps, but I'll be glad to run any tests if you need more 
assistance.

Thanks!
