Soundcard to output to AV amp

[Colbaker]

Hi all, Is there a soundcard that can output Via optical (digital coax second choice) to my AV amp in full dolby digital (the AV amp can also decode this so even if it just outputted the Raw info for the AV to decode?

Thanks

O.k. cool, I mainly want it for watching my blu ray disks in surround sound as at the moment my onboard realtek sound is only outputting to the av amp in PCM 96 which is basically stereo, So hopefully that card will work fine.
