Upgrading and Repairing PCs, Eighteenth Edition

Chapter 14. Audio Hardware

Since the first edition of this book was published in 1988, a lot has happened to audio hardware. Although rudimentary audio capabilities were part of the original IBM PC of 1981 and its many successors, audio was used on early computers for troubleshooting rather than for creative tasks. Computers used beeps for little other than to signal problems such as a full keyboard buffer or errors during the power-on self test (POST) sequence. The Macintosh, first introduced in 1984, included high-quality audio capabilities in its built-in hardware, but PCs did not gain comparable audio capabilities until the first add-on sound cards from companies such as Ad Lib and Creative Labs were developed in the late 1980s.
