I compiled envy24control from a recent CVS version.  It works and is
easily compiled all by itself.  Just go to alsa-tools/envy24control
and run ./cvscompile (IIRC).

This is a (serious) bug in the alsa-0.9.0rc6 ice1712 driver.  There is
a fix in CVS, but I'm not using that yet because of the inconvenience
of upgrading the drivers.

As a workaround, I use envy24control (compiled as above).  Under
"Hardware Settings" first set the "Master Clock" rate to "S/PDIF In".
Then, set it to "Int 44100".  For some reason, the rc6 driver won't
let you set "Int 44100" directly without using this trick.

Try a newer version of envy24control.  It's easy to do, and I think
you'll be please with the result.
