Hey! Who turned off the music? If you're having problems with your computer's speakers, you may be able to avoid an expensive repair by trying to fix the problem yourself, or with some driver updates. We'll show you how this works.
Method 1 of 3: General checks
Step 1. Understand the system
If you want to know how to troubleshoot your PC's speakers, it's a good idea to understand how it all works, at least on a basic level.
- Sound signals generated inside the computer are sent to the speaker output (usually green) of your computer.
- You connect your speakers to that port, and the sound continues through the wire to the small amplifier built into the speakers. This is exactly how your stereo is wired, only smaller!
- The output of the amplifier is connected to the speakers.
- The electrical current from the wall allows the amplifier to amplify your computer's low signal, strong enough to move the magnets in the speakers, causing the speaker's cone to vibrate, causing the air to bounce back. turns your eardrum back into motion.
- If there is a link in that chain of events that does not work, then the sound vibrations will no longer be transmitted. No vibration = silence.
Step 2. Insert headphones into the speaker port
With this you will immediately find out the most important thing: does sound come from the output of your computer. If you hear sound, then everything inside the computer will be fine and you have a problem with the speakers. If you don't hear any sound, don't worry about the speakers - try to figure out what's wrong with your sound card.
Step 3. Check the obvious things
- Is the volume turned on or off?
- Are the speakers connected?
Method 2 of 3: Headphones work, speakers don't
Step 1. It's not your computer
Armed with that knowledge, we will try to solve the problems with the speakers.
Step 2. Make sure the speakers are plugged in
Yes, that seems obvious, but maybe the dog ripped the cable out while chasing the cat, or maybe your daughter's lost gerbil chewed its way through your speaker wires.
Check the power cable. If your speakers have an adapter (like a black block in front of the wall outlet), check that to make sure it's warm. If so, it probably works fine. If it is cool or at room temperature, there is a chance that it has given up the ghost. This is not uncommon for adapters and it is not difficult to replace them. Take your adapter to the electronics store with your adapter and cable and they can test it for you and suggest a replacement.
Check the connection to the computer's speaker input. This connection is usually made with thin cords and small plugs, which are prone to failure. In particular, check the part where the cord meets the plug and see if the cord is split or torn. If you see copper or silver, chances are you've got the problem. If you are handy with a soldering iron, the solution is simple: cut off the old plug, buy a new one and solder the contacts of the speaker cord to the plug.
Step 3. Still Not Working?
If the connection is OK and so is the power supply to the speakers, then it can ultimately also be the speakers themselves. It's not easy to break speakers in a plastic case, so there are two more things to check:
- Open the speaker enclosures and check that the cord ends are securely attached to the back of the speakers. They may have fallen and the wires came loose.
- Check all wires inside the speakers. Are they all tight? If you see solder on the contacts (silver bumps on the wires where they connect), is it shiny and smooth or dull and uneven? In the latter case, you may be dealing with a "cold soldering tip," which does not conduct electricity well.
- If everything looks good and nothing is loose, then there is only one thing left: the amplifier in the loudspeaker housing. If there has been one, you can try to get it repaired, but it's probably cheaper to take the speakers to a recycling center and buy new ones yourself.
Method 3 of 3: Headphones don't work either
Step 1. It's time to do the obvious again
Make sure the volume is turned up and the output is turned on through your computer's audio player. I know it sounds like "did you plug it in," but very often something simple is the cause of the problem.
Step 2. Try the speakers on another computer
If they work on a completely different computer, then you have found another way to prove that there is nothing wrong with the speakers themselves. Time to go check the drivers!
Step 3. On a PC, open the Control Panel
Go to Start, click on Control Panel, and then on System and Security. Then under System click Device Manager.
Step 4. Double click on Sound, Video and Game Controllers
If a sound card is indicated, then a driver is present. If your sound card driver is not present, please install the correct drivers. There are a number of ways to do that.
Use Windows Update. Run Windows Update and let it download and install recommended updates. That way, you can update system functions and other software that can help fix the sound issues
Step 5. On a Mac, run Software Update
.. From the Apple menu, select Software update… It will check for system-wide updates and the sound card's built-in software.
Step 6. Install software from the sound card manufacturer
For example, if you got a disc with your sound card, it might contain the software you need. Run the installer and it will install or update your sound card driver.
Download the latest version.
Go to the website of the manufacturer of your speakers and search for the driver there. Find under Drivers, Downloads or Support - that's where they usually hide such software. Download the latest versions and install it.
Step 7. Still Not Working?
Go problem solving. If you're still having problems after all of the above, check every other audio output on your computer. If there are ports on the back and front, try one you don't normally use.
Also check the connection of the sound card in the computer, and make sure that it is properly connected. Look for the same things as inside the speakers: loose wires, bad solder points, or anything that looks like it shouldn't be
Step 8. If that doesn't fix the problem, take the bitch to the repair person and have them look at it, knowing you've done everything you could
Good luck and have fun listening!
- If you have problems with speakers that crackle or emit static noise, this can be caused by a router or a mobile phone. Mobile phones with GSM technology can also cause noise. Moving the speakers further away from the router or phone may help to resolve this issue.
Is your sound card built into the motherboard then don't try to remove it.
In that case, your entire motherboard will have to be replaced, or install a separate sound card and disable the built-in card.
- In some cases you can experience a lot of noise from the CD player or the Line In channels. You can easily solve this by lowering the volume or muting those channels via Volume control. (Start>All programs>Accessories>Entertainment>Volume control)
- Make sure to discharge the static charge in your body before opening the computer case. Static electricity can seriously damage the components inside your computer.
- Always make sure that your computer is not plugged in before opening the case.
