A colleague’s computer has an integrated sound card that your colleague wishes to upgrade. They install a new graphics adapter using a PCIx bus, but when they plug speakers to the new adapter, it does not work (even during boot up). Which step did this colleague forget?
  1. To install the Graphics Adapter device drivers.
  2. To disable the PCIx sound card.
  3. To install the latest Windows service pack.
  4. To disable the onboard sound card.
Explanation
Answer: D - If a new sound card is not working when an integrated card already exists on the system, it is likely the user forgot to disable the onboard sound card.

Key Takeaway: A computer with multiple sound cards doesn’t quite know where to send the sound. By disabling the on-board sound card in the Windows Device Manager, you tell the computer to disregard that one and favor the new one you have just installed.
