The "Digital" in speakers are for advertizing only. All speakers are analog. The Audigy has lots of digital music processing but has to convert these to a signal any speaker can use, so just plug your's in and you should hear music...
There are speaker sets that have digital input and onboard decoders for surround sound (which in turn feed the speakers). If this is what you're looking at then the Audigy can provide the digital feed to one of these sets.
