Once in a blue moon, I had to remove my old soundblaster card, boot up, boot down again, replace the card, then re-boot. For whatever reason, it worked just peachy. IRQ issue or me fudging something up, doing that procedure put things to rights.

Another problem can be related - boxes that aren't very rigid, and they pull the cards out when they change shape.
