If they claim it's "on-board" when, in fact, it's feature of the driver/software, then we should be able to make some money in a suit for false advertising. How do we find out which is true?
I'm reading this directly from the back of the Audigy box -
"Dolby Digital Decoding - Enjoy true 5.1 multi-channel playback in games with on-board Dolby Digital decoding capabilities. No need for a seperate decoder!"
The new Creative Sound Blaster Audigy has a Dolby Digital decoder built into the sound card which enables true 5.1 surround. According to the reviews I've read it has a much better S/N ratio than the competition. It also supports 24bit playback and does so with less CPU utilization than the Live. It also has a similar technology to QMSS where it can take a non-surround source (even monoraul) and project it into 3D space.
