Windows 7: Sound card messes with hardware interrupts (cpu drain)

Sound card messes with hardware interrupts (cpu drain)

HI. Its my first post and sorry my bad english. So cut to the chase - ive installed windows 7 ultimate 32 bit and what ive noticed was - high cpu drain from hardware interrupts.

I have two sound cards- first is Realtek HD which is integrated with motherboard. Second is SB Audigy.

Ive noticed some trick to clear the cpu drain from hardware interrupts to a normal size (close to 0%). The trick was to enter sleep mode and come back from it. But the problem was- my system was running quick and easy but without any sound ! Thats a common problem with vista and windows 7 that ive heard of.

So i took out the sb audigy and there is some small improvement. Cpu doesnt get that much load from interrupts (around 10 -20% less). I use now only Realtek HD and now the sleep mode option doesnt work because the interrupts drain stays aswell with the sound.

What to do ? Drivers as windows 7 says are - up to date. I guess that problem was even before installing w7, but then because of xp which works faster on my machine could have been unnoticed by me.
