Took the plunge and bought the Asus Strix Soar 7.1 Gaming Soundcard. After installing the card, I immediately went onto the Asus website and downloaded the latest drivers from the site. I configured my setup as 5.1 both in Windows 10 & the software. To my dismay, stereo sources doesn't get upmix to 5.1 at all, the sound only plays in two speakers out of the 5... I have to manually turn on the upmix in the software which actually makes the sound a lot worse. Both my previous X-fi extreme music and onboard sound did a much better upmixing job than this. Did anyone else here experienced this problem? For reference my speakers is the Logitech Z-5500.
