How do I connect computer speakers?

Updated: 10/07/2019 by Computer Hope

If you have trouble connecting speakers or headphones to your computer, try the following steps.

Connecting speakers or headphones to a 3.5 mm mini jack

Audio connections and their color-codings.

On most portable speakers, the right-channel speaker is the "main" speaker with the volume knob, and it often has two or more wires coming out of the back. One of these wires should connect to the left speaker, and another should have a 3.5 mm mini plug that connects to your computer's audio output jack. If your speakers require a power source to amplify the audio, there should also be a power cord. This cord needs to connect to a wall outlet or surge protector outlet.

In the back of the computer, connect the mini plug to the audio line-level output. This port is usually colored lime green, as in the picture at right.

USB speakers or headphones

To connect a set of USB speakers or headphones, insert the device's USB connector into one of your computer's open USB ports (as in the picture at right). The device should be automatically recognized by the computer. For additional information, consult the user manual for your device.

Laptop users

To connect speakers to a laptop with no sound out port, plug the mini plug into the headphones port.

Speakers with a subwoofer

If your speakers have a subwoofer, the right speaker plugs into the subwoofer. Make sure that your subwoofer is also turned on if it has a power switch on the back.

Can I plug speakers into a running computer?

Yes. It is ok to plug in and disconnect speakers while the computer is on and running. Most operating systems today also show a pop-up notice when speakers are plugged into the computer and disconnected.

Test the speakers

After the speakers are connected, adjust the volume to make sure it is not too loud or quiet by adjusting the volume knob. Open a sound or video file, put in an audio CD, or visit a site like YouTube to test the speakers and make sure they're working.

Do I need to install drivers for speakers?

No. Speakers do not need drivers. If no speakers are working with a computer, the sound card may need to have drivers installed.
