Computer audio output devices usually come pre-built into a laptop or desktop computer. What, if any, software is required for them depends on the device itself. Many devices do not require software but may require drivers.
Output DevicesAn audio output device is an internal or external sound card, or similar device, that is connected to a computer system. Most of these are "plug and play," which means that they do not require additional software. In some cases, listening devices such as speakers or headsets may be referred to as output devices but these take their signal from the sound card and are not directly controlled by software.SelectingIn some cases it may be necessary to select an audio output device. In the Windows Control Panel or the Macintosh System Preferences, an audio panel will allow users to choose the audio output device they would like to use. This is especially common where there are multiple output devices.SoftwareIn most cases no special software is required for an audio output device. Some devices do have software available that is meant to enhance the output signal and some devices require the installation, and sometimes updating, of drivers to function properly. The website of the device manufacturer will usually have up to date information on this. iPad to iTunes
