The term “audio output device” refers to any device that attaches to a computer for the purpose of playing sound. Speakers are the most common type of audio output device. Sound cards are a computer component that converts digital audio files into electronic sound signals. Device drivers are a small computer program that tells your computer how to access and use devices attached to it, including sound cards. Some specialized speakers and headphones require their own device drivers, particularly if they attach using a USB connection. An error message may be issued if a computer cannot find the device driver for its own internal sound card.”]
