Is this really valid?
My receiver cannot play this, the following plays as 
expected here (showing that eac3-over-spdif works 
fine on my equipment):
$ ffmpeg -i input -acodec eac3 -f spdif out
$ ffmpeg -f s16le -ac 2 -ar 192k -i out -acodec copy out.wav
$ mplayer out.wav -ao alsa:device=hw=1.7

I can make your file play but I wonder if I should...
(And yes, I do remember that this isn't your issue 
but I would still like to understand the issue first.)
