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 many require drivers

    Output Devices

  1. An 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.
  2. Selecting

  3. In 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.
  4. Software

  5. In 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.

If you received the error message stating "no audio output device is enabled" or "no audio output device is installed," the problem could be simply that the device is temporarily disabled. There is a multitude of reasons that a device could have been disabled. The installation of an unrelated program could have caused the problem, or someone might have accidentally clicked something to disable it. To enable the audio output, there are a few places you can check.


  1. Look on your Windows Taskbar, next to the system clock, for a small speaker icon. Right-click this icon and select "Playback devices." Look for "Speakers" under the "Playback" tab. If you do not see this, right-click the body of the window and click "Show disabled devices." This will add a check mark next to the text, which signifies disabled devices are being shown. Right-click the "Speakers" icon, or whatever audio output device you are using, and click "Enable." If "Speakers" is already present and has a green check next to it, Windows already has it enabled.

  2. Open your audio playback software, such as Windows Media Player, and look for a mute button. Usually, there is a speaker icon with a slash through it, if the program is muted. Click the icon to enable sound.

  3. Reboot your system and enter into BIOS or setup. The method varies between computers, but try continuously pressing "Delete," "F1," "F2," "F8," "F10" or "Esc" while the system is booting up. You will eventually enter the setup. Look for a tab which says "Hardware," "Devices" or "Enable/Disable." Locate your sound card, which may be integrated into the motherboard or installed as a separate card, and enable it. Do this by navigating with your arrow keys until it is highlighted, pressing "Enter" and selecting "Enable." Press "F10" to save and exit BIOS.

Windows 7 allows applications to take exclusive control of an audio device. When enabled, Windows 7 will playback sound in only one application, rendering other applications unable to output sound through the audio device. Sound playback may appear intermittent -- sometimes working, and sometimes not -- when in reality the audio device is playing back sound correctly and consistently based on its settings. Disabling exclusive mode will restore audio playback abilities to all of the applications on your computer.


  1. Left-click the Windows logo located on the left-hand side of the taskbar. Click "Control Panel." Type "sound" into the search box. Select "Sound" from the results.

  2. Select your playback device from the options on the "General' tab. Click "Properties."

  3. Click "Advanced." Uncheck "Allow Applications to Take Exclusive Control of this Device." Click "OK." Click "OK" again.

Tips & Warnings

  • Loose connections can also cause audio to play back intermittently. Confirm your speakers or headphones are plugged in securely to the correct audio jacks on your computer. Check the wires for damage or fraying.
  • Windows 7 can cause intermittent audio glitches when playing WAV files or streaming content in Windows Media Player. Microsoft is currently working to resolve this issue.
