Sound card product manager from Creative Labs Europe has confirmed that X-Fi PCIe 1X Fatal1ty Pro card indeed supports Dolby Digital live 5.1 over the optical port.
This is the first Creative card to support this very nice and neat feature. The card supports Dolby Digital live encoding and you can send good X-Fi and EAX powered sound in Dolby digital to your Dolby digital 5.1 compliant decoder, all via an optical cable.
This is something that you will get if you are a high-end sound freak and it is something that we really missed on the previous generations.
We have been waiting for this since the Nforce 2 Sound storm audio times, and Creative finally decided to implement it.
