None. > do you still get the clicks when the card is in loop-back mode? I think, occasionally. This can also partly (though not completely) be a problem of the signal source. Whatever the source of the problem, it would be easy enough to rectify it using multiple passes. >> So there is already something going on which I don't understand.

Try changing the "IEC958 In Phase Inverse" switch. Of course, I tried that. IIRC it might possibly changes the overall sound of the noise, but does not change it from being noise. And once the card is in working mode, I don't think it makes a difference. >> So what would one actually have to do to have the "incoming spdif >> clock" respected? > > There is nothing to set on this card.
