Where to Connect Audio Cable on Motherboard: A Complete Guide

The need to attach an audio cable to a motherboard is a common occurrence for PC enthusiasts. The question is whether you know where to plug in the audio connection on the motherboard. This tutorial aims to show you how to plug in an audio wire to your motherboard methodically.


The motherboard is the central component of your computer, as it links together all the other parts. An audio cable is one of the many cables that can be plugged into the motherboard. Connecting your computer’s speakers or headphones to your computer’s audio output requires an audio cable.

If you’re not used to assembling computers, connecting audio to your motherboard could seem daunting. It may initially seem difficult, but you can accomplish it independently with the appropriate instructions.

So in this Comprehensive guide, we will discuss Where to Connect Audio Cables on motherboards in detail.

Understanding Audio Cables

One method of transmitting audio signals from one device to another is via audio wires. Many variations of audio cables exist, each with its advantages and disadvantages.

The 3.5mm audio cable connects headphones and speakers to personal computers and mobile devices. This cable normally transmits stereo audio and has a jack on each end.

The RCA cable is another typical audio cable that links devices with a stereo. Each end of this cable contains two connectors, one for the left audio channel and one for the right.

Audio cables come in various shapes and sizes, with analog and digital varieties used to transfer sound. These cables can carry 5.1 or 7.1 surround sound signals and are often connected via optical or coaxial means.

It’s crucial to think about cable length, connector type, and sound quality while shopping for an audio cable. In addition to ensuring the cable is high quality and works with your devices, you should check to see if it is compatible with your equipment.

The Audio Connector on Motherboard

An audio connector on the motherboard can be found on the back or the front of the computer casing. The audio cable attaches to a tiny rectangular connection with multiple prongs.

If you look at the audio connector on the motherboard, you’ll probably notice it’s colored green, which means it’s the output jack. The audio jack’s labeling options include “Line Out” and “Speaker Out.”

Types of Audio Connectors

You can attach either a front-panel audio connector or a rear-panel audio connector to your motherboard if you need to use either one.

Front Panel Audio Connector

The audio wire from the front panel jacks is connected to the motherboard via a connector normally positioned on the front of the computer case. Typically, a single-row, the 9-pin connector is used for the audio input on the front panel.

Rear Panel Audio Connector

Connecting the audio connection from the jacks on the back of the computer to the motherboard requires a rear panel audio connector. Often, a rear panel audio connector will have multiple rows, with each row corresponding to a separate set of audio channels.

Where to Connect Audio Cable on Motherboard

Plugging an audio cable into the motherboard’s audio connector is the simplest method for connecting an audio device to the motherboard. While attaching an audio cable, one can use either the front or the rear panel audio connector, each with its unique procedure.

Front Panel Audio Connector

Here’s how to plug in an audio cable to the port on the front panel:

  • Find the audio input jack for the front panel on the motherboard.
  • Plug the front panel audio jacks into the motherboard’s front panel audio connection.
  • Verify the audio cable is firmly plugged in, and that the pins are inserted into the correct holes on the connector.

Rear Panel Audio Connector

Steps to plug an audio cable into a back panel jack:

  • Check the motherboard for the audio jack at the back.
  • You’ll need to run a connection from the back panel’s jacks to the motherboard’s rear panel audio port and then plug the cable into the appropriate channels there.
  • Ensure the audio cord is firmly attached to the jack.


When connecting the audio wire to the motherboard, you may experience problems with the sound. What follows are some frequent concerns and their answers:

Audio Not Working

After plugging the audio cable into the motherboard, if the sound still isn’t coming through, try these steps:

  • Ensure the audio wire is properly connected to the motherboard’s audio jack.
  • Verify that the audio output jack is connected to the speakers or headphones.
  • It would be best to double-check the configuration of your computer’s audio settings.

Static or Distorted Sound

After connecting the audio connection to the motherboard, if you have static or distorted sound, try the following:

  • Ensure the audio wire is properly connected to the motherboard’s audio jack.
  • Verify that the audio output jack is connected to the speakers or headphones.
  • If you’re having trouble hearing anything, ensure your computer’s audio settings are set up correctly.
  • To fix audio issues, update your computer’s drivers.


Plugging in an audio connection to your motherboard is an easy way to improve your computer’s sound quality. The audio cable’s connection to either the front or back panel audio connector is simple and can be accomplished without assistance.

You should now be able to connect an audio cable to your motherboard with the help of this guide. When problems arise, see the troubleshooting section for advice on how to fix them.


Can I connect multiple audio cables to the motherboard?

You can connect multiple audio cables to the motherboard with the appropriate connectors. Follow the manufacturer’s instructions and avoid overloading the audio input.

Can I use any audio cable to connect to the motherboard?

No, you cannot use any audio cable to connect to the motherboard. You must use the audio cable compatible with your motherboard’s audio connector. Refer to your motherboard’s documentation for more information.

How can I check if the audio settings on my computer are properly configured?

To check if the audio settings on your computer are properly configured, go to the sound settings in the control panel or system preferences and ensure that the correct audio device is selected and the volume is not muted.

What should I do if the audio output is still not working after troubleshooting?

If the audio output is still not working after troubleshooting, you may need to update your audio drivers, check your audio cables, or consult a professional technician for further assistance.

Can I connect the audio cable to the USB port on the motherboard?

No, you cannot connect the audio cable to the USB port on the motherboard. The audio cable must be connected to the audio connectors on the motherboard, which are separate from the USB.
