I tried this out and my experiment proved Ralph correct:
Pin 4 on the center 10 pin/2 row connector on the board does
carry an SPDIF signal which I can play back on my HiFi system,
but it is only plain stereo, not AC3 (I tried the AC3 promo
channel with APID = 256 and also Pro7 with APID = 101 and some
PIDs in the neighbourhood of these).
I also had the impression that the sound quality I got from that
pin 4 was surprisingly poor (high-pitched sounds hissed a little).
Did anyone else try the SPDIF output?
It seems kind of odd to me that the DVB-S card neither outputs
Y/C video nor AC3 sound. Isn't perfect picture and sound quality
the whole point of DVB?
