The piece of software known as kX by Eugene Gavrilov is amazing. 'How did the author achieve this' was my first thought upon reading about it's capabilities. That being said, it's my hope to get 5.1 games upmixed into 7.1 since a lot of them lack the feature. Not sure if that's even possible but still trying and so far got my sb0423 10k2 modded for analog 7.1, without those 4 pole camcorder cables, here's how. this looks rough atm but is just a proof of concept and you can always make it more neat. hxxp://i.imgur.com/T8B48v2.jpg (i'm a new user so change the xx to tt) Now, my next hurdle is to get the dsp tackled. If we clear the dsp window, should we still get sound in windows? My fear is mine's not working because it doesn't do anything after following the dsp tutorial written by Lex Nahumury.
