So I misread that one. Thought that there was a break inserted by
someone, and the line should read: "IEC958 (S/PDIF) Digital Audio
Output null".

So everything looks ok, but there is no sound :-( .
There are 2 additional code paths (4 choices in total):
1. Switching to professional transmission:
setting 'ac3SpdifPro = true' in audio-alsa.c, line 41.
2. Different open for AC3 with patch from Roland Praml found here:
http://www.vdr-portal.de/board/thread.php?postid=506499#post506499
Patch includes enforcing of spdifpro mode.
If you need help, please ask again.
