I recently purchased a Xonar DG under the assumption that it had Dolby virtual speaker (5.1 simulation from 2 speakers), as most of the review sites mentioned this (bit-tech/message boards). After trying both the official and the unified drivers, I see this option nowhere. I have a Xonar DX as well and I see the option right below 7.1 virtual speaker shifter. Were all the review sites just wrong? This card doesn't seem to have dolby virtual speaker.
I've attached a screenshot of my Xonar DG control panel.
