Ok, so im upgrading my PC, and decided that I want to use my XP500 turtle beach headset for game audio, to do this, I learned that I had to buy a sound card which would support digital output SPDIF. I went and brought a ASUS Xonar DG, as it supported digital, after installing the card and the drivers, it comes up as multiple devices in my devices list. the problem is, after plugging in the XP500 digital cable to the sound card and the reciever, no sound comes through my headset. I know that the card is installed correctly because i can plug jack into it and hear sound through my speakers, just no sound through the digital output, any help would be appreciated here guys, and I apologise in advance if this is the wrong category to post this under
