I have my Audigy2 attached to my Creek receiver via a Koss RCA to mini cable. It sounds great except that there is so much noise and static at high(ish) volumes. At a decent volume, I cannot hear it, but the higher I turn the volume, the most prominent it is. Obviously I cannot hear it unless I have my ear next to the speakers, and definitely can't hear it when music is playing, but it's annoying nonetheless.
When I am using headphones, the difference is much more apparent. When I move my mouse, I can hear it, and when my hard drive works, I can hear that as well, through my headphones! I know it's not the receiver because when I unhook the RCAs from the back of the receiver, I hear nothing.
I've heard the argument that it may be an IRQ inference. Well, it's not, because I tried changing my sound card's PCI slot, changing the IRQ manually via the BIOS, and I still got nothing.
Anyone know what's going on?
