This is a question I also have and never got an answer for.
I had working spdif and I rely a lot on spdif, but it suddenly stopped 
and I could never get it going again. 5 months pending post on alsa 
group, no response asking exactly the same thing. LAU also blank.

I know my post is slightly against the rules as it can be viewed as an 
Atta Boy, but if it helps motivating someone in the know to explain this 
I think we will be both very pleased.
At the moment with alsa SPDIF I get a "clock sour" error message and no 
way to sort it out.
Your question lies at the heart of that, as I can maybe use a different 
clock source to get spdif to work again.
