It's important to understand that just because a DAC has VSS enabled, doesn't mean that their optical out is sending that VSS. Something like the Mixamp 5.8. If you turn on VSS, the DAC won't send that. Why? Because the optical out in this device is passthrough only. Meaning it's sending the same signal it received. Nothing the DAC did to alter it to turn it into VSS affects this.
The G6 and Xonar U3's optical out isn't passthrough. The signal they send out is affected by the DAC unless you enabled line out mode, where it won't touch the signal.
Ngl i read it 3 times and now i understand it haha! It's nice to know that most devices are passthrough only. For me it shouldn't be a problem as i looking for a non gaming dac (like topping) which gets feeded by optical input / VSS signal (PC software like atmos). My guess is, that it should work aswell, if the game supports a virtual sound like overwatch for example?
