sound card with coax out raw ?

[T C]

is there a cheap sound card that has raw digital coax out for 5.1 ?
i believe my audigy 2zs doesnt output to 5.1 am i right ?
its for a media box so its going to go straight into an av amp and the optical in on the amp is already used up

just need to add this will be for playing movies only usually xvid, divx with dts

if you are playing a movie with a dd or dts soundtrack, any soundcard will output that soundtrack via the spdif optical or coax connection
