Pardon my previous enthusiasm. So many months debugging!
I've straightened my tie and regained my composure now.
I tried creating a new asound.state with alsactl.
The resulting asound.state was smaller, but did not fix the problem.
I also tried manually turning the 'IEC958 CS8427 Error Status', and the
other related controls, on/off with a mixer, no luck.
I know the two cards are locked because if I disconnect the S/PDIF cable,
the ice1712 card goes silent or makes noises. This is normal behaviour.
Also, I have run this setup for hours without an xrun or 'un-synced drifting'.
You know, the 'locked/no signal' indicator never has worked right.
In ALSA 1.0.9b it always just says 'locked' (see below).
In ALSA 1.0.15 it says 'locked' only when on a fixed internal rate.
** Here is some info below which I think will help.
It seems to me, looking at the 'IEC958 CS8427 Error Status' results below,
that envy24control should perhaps be using it, instead of
'Word Clock Status', as a 'locked' indicator.
Thanks again. Tim.

Note: I could not find a 'Word Clock Status' item.
Perhaps that's why it never worked at all under ALSA 1.0.9b ?
