Did some more digging, discovered a fix that worked for me but may not apply to everyone.
My specific issue is apparently a problem with Logitech wireless headphones not working correctly unless the transceiver is plugged into a USB port that is a part of the motherboard. Anything else (front jacks or a USB hub) and surround sound is disabled without Windows being notified, so your computer keeps sending 7.1 sound to a now stereo headset. As soon as I plugged into the back of my PC the voices started working perfectly.
Hope this helps someone else!
