And if removing and replacing the card doesn't make the system reallocate an unused interrupt then you can always try removing the hardware device entry in the Hardware Device Manager and try reinstalling. Though there is no reason that a card that was previously working with its assigned IRQ should suddenly have problems. But installing another device could cause this sort of a problem if you have run out of available IRQs. You can check IRQ conflicts & sharing ( which is valid in some cases ) by going to Start - Programs - Accessories and running the System Info utility which will list what is using the IRQs, so look there to see what is trying to use the same IRQ as your soundcard. It may at least pinpoint the source of the problem.
