And after all that if you go into Windows Sound, and right click your main output device (for me it just says speakers on Sound Blaster Z) and hit configure, its on 5.1 and not 2.0/stereo, thats the issue were having, you can set it to to 2.0/stereo, but once you reboot/wave from sleep, it defaults back to 5.1 with the headphone port
That is interesting. I never noticed that before. I get the same configuration display in my Windows.
However, since I bypass Windows Audio completely in my configuration via WASAPI Event Style (using J River 18), I get Headphone Stereo 2.0 through my ZXR, no matter what Windows says.
