ur UI seems to tell me that your driver is not the latest, since if u do have the latest, u'd have a graphic equalizer, which you dont...
Which brings another question; What's the latest driver? I've been looking around but the version is 2.51, while mine is 5.10.xxx
A direct link would be very helpful
BTW, my Realtek HD Sound Effect Manager does have a graphic equalizer. I'll upload the picture ASAP
