My IDT sound card runs perfectly on my laptop except cannot work after wakeup.

Any one has solution to that?

Moreover, my computer cannot go to sleep automatically, could only sleep by clicking "Sleep" in Apple menu.
Is there anything to do with that?

raiden i used ur guide and i have the same computer as you. the only thing is with my speakers they dont work after sleep but they also play out of the speakers and headphones at the same time when headphones plugged in. did this happen to you? if i did how did you fix it?
