If your computer's speakers aren't working and you don't want or can't get them to a professional, you can learn how to diagnose and repair them yourself. This type of repair requires a great deal of technical knowledge, but most malfunctions that affect speakers are caused by easily repairable hardware and software problems.

Steps

Part 1 of 5: Perform a comprehensive check

Fix Computer Speakers Step 1

Step 1. Know how your speakers work

To know how to solve speaker problems, it is good to know the basics of how they work.

  • Sound signals generated inside your computer are sent to the audio port (usually green).
  • You plug your speakers into this port and the sound passes along the wire to the small built-in amplifier.
  • The output of the amplifier is connected to the speakers.
  • Power, which comes either from the battery (for a laptop) or the wall outlet (for a desktop) allows the amplifier to amplify the tiny signal coming from your computer into something powerful enough to vibrate the speaker magnets, causing their cone to vibrate, which in turn vibrate the air, creating sound.

Step 2. Know what may be causing a malfunction

Although any failure in the chain of events listed in the last step could cause your speakers to malfunction, there are 2 main reasons why you may not have sound.

  • A software glitch: Software glitches can occur as a result of many factors ranging from insufficient power on a laptop to outdated drivers or audio settings.
  • A hardware problem: Hardware problems are caused by parts of the enclosure that are physically damaged or loose. If your speaker hardware is damaged, there's very little chance you'll be able to fix it yourself (and that's next to impossible if you're using a laptop).

    The only exception is if your speakers are not properly connected to your computer

Step 3. Make sure your laptop is plugged in

Many Windows laptops go into low power mode if their battery drops below a certain threshold, which can cause certain functions (such as sound) to malfunction. You can avoid this problem by plugging your laptop into a wall outlet.

Of course, this will not be necessary if you are using a desktop computer

Step 4. Check the volume of your speakers or your computer

If your speakers have a separate volume control from your computer, make sure the volume is set to a level where you can actually hear them. It sounds obvious, but checking for an accidental mute is quick and more common than you might think.

If you have a laptop instead of a desktop, make sure the volume is on maximum

Step 5. Make sure you don't have a headset plugged in

If a device is plugged into the headphone jack on your computer, the speakers will not work.

  • On some desktops, the headphone jack is located on the back of the tower.
  • Many speakers have their own headphone jack, so check the connections there as well.

Step 6. Turn off Bluetooth on your computer

Sometimes your computer can connect to an external audio source (for example, a soundbar or a car) without you realizing it, making it look like the audio output is not working.

  • On Windows: press ⊞ Win + A (or click on the box in the lower right corner of the screen), then click on the colored Bluetooth icon

  • On Mac: click on the Bluetooth icon

    Macbluetooth1

    at the top right of the screen then select Turn off bluetooth from the drop-down menu that appears.

Step 7. Test the sound with headphones

If you have determined that your speakers are not working even if the headphones are not plugged in, listening to sound through headphones will help you know whether the problem is with your computer or not.

  • If the sound from your computer is going through the headphones, but not through the speakers, then the speakers or their connections are the problem.
  • If sound from your computer still does not come out through the headphones, you are dealing with a software problem.

Step 8. Check your speaker connections

Your speakers may not be properly connected to the computer (or to each other). You can check their connections by looking at the cables that run between them on the back of each sub, and you can check their connection to your computer by looking at the connections on the back of your machine.

  • Your speakers should be plugged into the “Audio Out” port on your computer, which is typically a green headphone jack on Windows desktop computers.
  • If your speakers connect via HDMI, an optical cable, Thunderbolt, or the like, make sure the connections are tight.

Step 9. Restart your computer

This will help you resolve most temporary software issues. The best way to restart your computer in this kind of situation is to shut it down, wait a few minutes, and then turn it back on.

  • On Windows: open To start up

    Windowsstart

    , click on On Off

    Windowspower

    , select Stop, do not touch your computer for 5 minutes and then press the power button.

  • On Mac: open the apple menu

Advice

  • If you are looking for drivers for your speakers, you can visit the manufacturer's website to download them. Usually you will find them in the “Support”, “Downloads” or “Help” section.
  • If you just bought your speakers that don't work and are still under warranty, bring them back and ask for a replacement. Don't try to take them apart.
  • You can check the welds as well as the internal wiring of the speakers by opening their boxes. This is not recommended unless they are already old or out of warranty.

Warnings

  • It is often cheaper to buy a new pair of speakers than to have damaged ones repaired.
  • Disassembly and physical repair of the speakers requires a great deal of technical knowledge. Unless you know what you are doing, do not attempt to re-solder or repair internal parts.
