I just got an Audigy2 Platinum and expected it to be splendid. Well..... I've had some serious difficulty with it. There are multiple places to adjust the sound. 5.1 passthru, speaker settings, etc. It is a bit confusing and the documentation sucks. I'm going to call soundblaster support tomorrow, but I thought I'd post here to see if this is a common problem. Right now what I am getting is two different issues. My PC speakers are picking up alot of noise from the system. I can hear a slight backgtround noise when the HD is accessed or the mouse moves, etc. It is slight but noticeable. I also am having trouble with the SPDIF out. I've been tweaking the hell out of it and am not sure that I am getting a 5.1 signal out of it. (I think so, but not sure) The receiver seems to think it is 5.1, but the sound is very flat. Explosions no longer rock the house. I have to turn the volume higher than I did with my old DVD player and there is slight but noticeable noise too. It is different sounding from the PC speakers noise - more like static. I placed it in the bottom slot, furthest from my aiw9700 and second furthest from my radeon7000 (monitor/projector). It is a pentium system, Asus p4p800 (disabled onboard sound). One more thing, when I hook the SPDIF up to the AIW output with their adapter there is no sound. There are just too many options and I'm stuck.
