If you are handy inside the computer - unplug it - remove the side cover - one hand on the case briefly (ground yourself - no static) and remove and re-insert the sound card.
No Joy ? - try it in another slot. Be sure to ground yourself to the case first.
If it is an integrated card , part of the motherboard, then it may be an issue relating to USB, the power supply and the MB.
please post the model sound card you have or MB model or computer model if known. I will see what I can find.
Oh, and try plugging a set of headphones into the card's output. Perhaps there is an issue with the speakers and the printer.
