This has been tried before, this is my latest attempt and educating people on PC audio do's and donts, and clearing up a lot of myths surrounding the subject. Out of arrogance i'm going to sticky this, because i think its worth it. Dedicated vs Onboard + Analogue sound quality Analogue Vs digital SPDIF vs HDMI How to setup 5.1 sound Positional audio Vs Surround sound Fake surround sound EAX in the modern gaming world And a bonus: 16 bit audio vs 24 bit read this to see that some people think 24 bit audio aint worth it. arguments abound on this one. Sticking your audio straight to 24 bit in the windows control panel may not actually give you better audio, test it and see for yourself.
