Have you tried to connect card 1's spdif out to 2's input and set 2's
clock to spdif in.
I think only way to get anything properly from spdif in is to clock the
card from the spdif in also.
However, sometimes my Audiophile card receivec stuff from spdif even it's
not clocked from it, but then I get pops and cracks on leftf channel, and
sometimes I hear nothing. But both issues disappear when clocking from
spdif.

Don't know.

No you don't. My .asoundrc has
pcm.spdif_test
{
type plug
ttable.0.8 1
ttable.1.9 1
slave.pcm {
type hw
card 0
device 0
}
}
and I can play & capture using this 'spdif_test' device. This is for
Audiophile, but since they use same chip, this should work for you.

story.
You can connect inputs to outputs directly with the envy24control and it's
done in hardware.

ps. One more thing, make sure you use the right connectors when connecting
physically the spdif inputs and outputs.
