To disable speakers when headphones are plugged in, open Realtek HD Audio Manager, Speakers tab, click device advanced settings and select "mute the rear output device, when a front headphone plugged in". That's it. As for the static you're encountering, it isn't normal. I haven't heard any static at all even at high CPU loads.

Please remember that Audigy 2 was originally released in September 2002. It is old. The Audigy 2 chip itself shouldn't cost more than maybe $5 at most now when mass produced.
The biggest advantage of the old Audigy 2 series over the current HD Audio chips is hardware acceleration of EAX, DirectSound3D and OpenAL. But if hardware acceleration in games is what is important, why would you still use Audigy 2 instead of getting cheap X-Fi Xtreme Audio for $50 if not less?
No way HD Audio chip can beat SB X-Fi , Auzentech X-Plosion, Razer Barracuda AC-1 or Asus Xonar.
But has it caught up with almost 6 years old Audigy 2? Definitely yes.
