I recently purchased a plyr 1 headset and it work really well with my ps4 but I looked into getting it working with my PC and after everything I read up on I figured I just need a Dolby digital sound card and it should work with my headset with Dolby surround. I went and purchased a asus xonar DX and hooked it up to the plyr 1 transmitter using optical. After testing it out I was let down that the surround wasn't working. Is there some step that I missed?
