Just for your info, I have been looking over the alsa mailing list 
archives, and AC3 is not going to work unless you can do the following: -

SPDIF out from Crystal CHIP linked to another sound card that can do 
SPDIF in. This other sound card has to be supported for SPDIF in with 
linux. i.e. NOT SB Live, SB Audigy etc.

I have verified that a Motherboard based sound card with the Intel ICH5 
chipset with an ALC650 has an SPDIF in that works on my machine.

The reason for this SPDIF out -> SPDIF in is so we can actually verify 
which SPDIF info bits are being set. There seems to be no clear 
understanding yet, of what bit does what in the cs46xx driver.

The most likely cards to work for SPDIF in are actually the cheapest 
onces, because they are unlikely to have re-samplers etc.

Cheers
