Looking for a low profile sound card with digtal output

I am looking for a low profile sound card with digtal output. I have a set of Boston Aucustic speakers that has a plug for digital output. I have a Dell GX260 that is low profile but the onboard sound is just analog. If anyone has any suggestions, my ears are open.

Thanks,

Look at the specs here - they used Sound Blaster on your comp.
