A audio card is a device that processes audio information from your computer and sends it out to audio devices like speakers, headphones and microphones. Just like video cards, DVD drivers and other hardware devices on a computer, sound cards require a software component (driver) to tell the computer how to properly utilize the device. Therefore, whenever a new sound card is installed or a new operating system is being used, audio drivers need to be installed for the audio to work.
