I have in the past forgotten to check the settings with envy24util or
mudita to verify clock selection.
If the clock selection defaults to S/PDIF input as clock source, but no
S/PDIF signal is available, the ICE1712 cards stop with a clock error.

Sample clock not running properly may cause a similar error.  May not be
related at all, but easy to check with envy24util to verify clock is set
to "internal" to eliminate as a possible cause.
