Yes, as VDR User said, the latest generation VP4/VDPAU feature set C
cards (GeForce 210, GT 220, ...) have an integrated audio controller.
The ALSA driver should support 7.1 channel PCM too.

Some older cards have an S/PDIF input header but they don't support
multichannel PCM, obviously.

IMO the only reason to go for a separate card over ION would be higher
quality 1080i deinterlacing. You'll need GT 220 for that since GeForce
210 is only slightly faster than ION. They have the same video processor
and therefore the same video decoding capabilities, but post-processing
is done on the graphics cores.

ION2 has VP4/C, I think.

If you don't need advanced 1080i deinterlacing, Asus AT5IONT-I is a very
good option right now. It has ION2, latest dualcore Atom and USB3, and
it's passively cooled.
