It appears that the current version of envy24control is broken.
I've just tested alsa-lib-1.0.16 with envy24control from
alsa-tools-1.0.16 and it is behaving strangely. 
It doesn't show the correct sample rate as set by jackd,
and doesn't switch between S/PDIF and internal clocks correctly.
I've tried it with 2.6.20 and 2.6.25 kernels and it's the same
with both. I'll report it on the alsa-devel list.
