Can someone please help me?

i have a problem with putting 3 soundcards on my pc i tried 2 soundcards on 2 separate ICQ slots .. but the problem is that when i play then simultaneously, there seem to have crackling sound on the shared IRQ soundcard.. can any1 recommend any motherboard that can support 3 soundcards without any shared IRQ slots? by the way can 3 soundcards be played simultaneously on a motherboard? is this possible.. i need to know this and i dont care how much it costs i thank you all in appreciation first...
