Clemens - thank you!!! I have been trying for several months to fix this. I am now listening to the card via SPDIF for the first time! My apologies over the two sends to alsa-dev - I sent the first one before my registration to the mailing list was approved and hadn't seen it appear on the list today after my registration had been complete for a day, so I assumed it had got dumped because I was not a list member when I sent it. So I resent it today. I will only send once for future problems, apologies.
