3DsoundSurge FAQ Manager v1.0: S/PDIF: The S/PDIF port is treated as just a simple output for the front channels during normal usage (not dvd playback). Does Aureal plan to send the 4 speaker channels through the S/PDIF port in AC-3 Dolby Digital 2/2 mode or even 3/2 mode(front/rear) to allow a S/PDIF connection to a Dolby Digtal home theatre setup to use four speakers?

When you send normal audio out the S/PDIF, it will only send the front stereo signal. There is no way currently to send the signal going to both analog jacks. In order to send front and rear, the hardware would probably need to encode the streams on the fly into a Dolby standard for your decoder to decode. Considering the cost of such an endeavor (in terms of engineering time, money to Dolby, and CPU usage to encode) this is very unlikely. - Updated: November 29, 1999
