Hi, Just installed said card with newest official drivers but the sound is very echo-ish whike playing games,I have all effects off Im using roccat kave 5.1 headphones,audio center set to 6 channels,I can get rid of the echo by switching to 2 channels but I want 5.1.I think this is a common problem does anyone have a fix or do I have to live with asus shitty drivers!
