Can't assign dedicated IRQ to sound card - to much on same IRQ
Greetings!
I'm not sure if this is MOBO related and/or Win 7 Pro.
In short terms, Win 7 Pro have assigned VGA and my sound card to same 16 IRQ number. Plus a several different PCI and USB controllers has been assigned to same IRQ.
That architecture is causing much clicks and pops in Cubase 5/6. I had same problem before in old DAW:s. But then, assigned sound card to different, dedicated IRQ - solves the problem on the spot. Well that was in old good days with Win 98, 2000, XP :)
For the moment, I was able to disable some USB controllers away from shared shared IRQ with noticeable better results in audio performance, but unfortunately the side effect was blue screen every time I turned off or restarted PC. Maybe I haven't done it proper way?
Now I think that I have following options and I need help to realize some of them:
1. Assign dedicated IRQ number to PCI-slot sound card;
2. Make as much as possible space on that IRQ so that PCI-slot sound card can work frealy;
3. Reinstall Win 7 with sound card present in PCI-slot and hopping that Win 7 will give it another IRQ?
3. Assign a dedicated IRQ to VGA card;
4. Re-alocate PCI-slot sound card into PCIEX1_1 slot with this adapter: PCI Express to PCI Adapter (Will Win 7 assign different IRQ then??)
5. Replace my current GA-X58A-UD5 MOBO with some from GA-P55 line as they have 3 x PCI slots.
During Win boot this shows in "PCI device listing"

I will really appreciate if someone could give me some help so that I can get rid of this nightmare.
