What to do if the columns stop working: a complete guide

The sudden disappearance of sound at the most crucial moment - whether it's the final battle in an online shooter, an important video call or the culmination of a favorite movie - is always irritating. The situation when columns stopped workingIt can occur for a variety of reasons: from a banal cable torn to complex software conflicts of the operating system. Before panicking or carrying equipment to the service center, it is worth conducting an independent diagnosis, which in 80% of cases allows you to bring the sound system back to life.

Modern acoustic systems, whether they are multimedia JBL, studio monitors Yamaha Simple computer acoustics are a chain of devices where failure is possible at any stage. This can be a physical break of the wire inside the cable, oxidation of contacts in the connector 3.5 mm, failure in operation. sound-driver or even accidentally switching the default output device in Windows settings. Understanding how this chain works is the key to solving the problem quickly without unnecessary costs.

In this article, we will discuss the algorithm of actions from simple to complex. You will learn to distinguish between software glitches from hardware breakdowns, learn how to check the integrity of plumes and update sound card software. If after all the checks sound will appear only when you connect the headphones, then the problem lies in the speakers themselves or their amplifier, and not in the computer. Let’s go through all the stages of recovery.

Primary Diagnostics and Physical Connection Check

The first thing to do when you find out there is no sound is to check the obvious. Often the reason lies not in complex electronics, but in elementary inattention. Make sure the speakers are plugged in (if they are active, i.e. have their own amplifier) and the power indicator is on. Check the volume control on the body of the acoustic system itself: it could be accidentally twisted to zero or put into mode Mute.

Carefully inspect the cables. Wires connecting speakers to a computer or phone are often mechanically affected. They can be clamped with the legs of the table, pulled by pets or gnawed by toothy pets. Try to slightly move the cable at the base of the plug and at the entrance to the column. If there are wheezing or interruptions, then contact is broken.

Pay attention to the correctness of the connectors. Classic PC acoustics use color coding: green-jack Line Out is for the main speakers, pink for the microphone, and blue for the linear input. If you stick a plug in a pink nest, there will be no sound, as it is the entrance for recording, not the exit.

• 🔌 Check if the 3.5mm plug or USB cable is tightly inserted before the characteristic click.
• 🔋 Make sure the power indicator on the speakers is on and the batteries (if wireless) are charged.
• 🔊 Make sure that the volume control on the column body is not at a minimum.

⚠️ Note: If you use active powered speakers, never attempt to repair the power supply yourself unless you have the appropriate qualifications. The capacitors inside can retain charge even after being turned off from the outlet.

If the visual inspection did not give results, try connecting the speakers to another device. Connect them to a smartphone, tablet or other laptop. If the sound appeared, then everything is fine with the acoustics, and the problem should be looked for in the settings of your main computer. If they are silent there, then there is probably a malfunction inside the speakers themselves.

Configuring playback devices in the operating system

It often happens that everything is physically fine, but the operating system does not “see” the connected acoustics or sends the sound stream to the wrong place. With Windows 10 and 11, the management of output devices has become more flexible, but also more confusing for the untrained user. The system could automatically switch to HDMI audio output to a monitor (which may not have speakers) or a virtual audio device.

To check this, right-click on the speaker icon in the tray (near the clock) and select "Open sound parameters". In the window that opens, find the "Select the output device" section. Click on the list and try to go through all the available options. If you have speakers connected via USB, they can be displayed as a separate device with the brand name, for example, a sign of the brand. Logitech or Creative.

Sometimes the device can be simply turned off software. For a deeper check, press Win + R- Get the command in. mmsys.cpl and press Enter. The classic Sound window will open. Go to the "Reproduction" tab. If you don’t see your speakers in the list, right-click anywhere in the list and tick “Show Disabled Devices” and “Show Disabled Devices.”

If your speakers appear in the list but they are gray, right-click on them and select "Enable". Then again, the right button is "Use by default." After that, the status should change to "Ready" with a green tick. This action will force the entire audio stream to this acoustic system.

• 🖱️ Right-click on the sound icon and select "Sounds" to access the full menu.
• ✅ Make sure that the list of devices has a green tick opposite your speakers.
• 🚫 Check if the ban icon on the output device is worth it (means it is disabled).

Diagnostics and updates of sound card drivers

The driver is the intermediary between the operating system and the hardware. If this software layer is corrupted, outdated, or conflicts with Windows updates, the sound may disappear completely or work with distortions. Users often ignore updates until they encounter a problem. In the device manager, you can see the state of the sound controller.

Right-click on the Start button and select Device Manager. Open the branch "Sound, gaming and video devices". Here you will see the name of your sound card, most often it is Realtek High Definition Audio, Conexant Or the name of the motherboard chipset. If a yellow triangle with an exclamation point is burning next to the device, then the driver is working incorrectly.

The most reliable way to fix the situation is to remove the current driver and allow the system to install it again. Right-click on the device and select "Delete the device". In the window that appears, tick the “Delete driver programs for this device” box (if such an option is available) and confirm the action. After that, be sure to restart the computer. When booting, Windows will try to find and install a standard driver.

devmgmt.msc

This command opens the Device Manager directly, bypassing the Start menu. If the automatic installation didn’t help, visit the website of the manufacturer of your motherboard or laptop (for example, the manufacturer of your computer). Asus, MSI, Lenovo) and download the current audio driver for your model. Installing drivers from universal aggregator sites often leads to the installation of adware or unstable versions.

In some cases, the driver rollback helps. If the sound has disappeared after a recent Windows update, open the properties of the sound device in the Manager, go to the Driver tab and click the Reverse button if it is active. This will bring back the previous, stable version of the software.

Verification of Windows Services and System Files

A special service is responsible for processing sound in the operating system. If it is stopped or is working manually, there will be no sound under any settings. This is a common problem after optimizing the system with various “accelerators”, which turn off unnecessary processes, in their opinion.

Press. Win + Renter services.msc and press Enter. In the list you can find the service Windows Audio. Double-click on it. In the "Startup Type" field, the value "Automatic" must be selected. If the service is stopped, press the "Start" button. Also worth checking out is the Windows Audio Endpoint Builder service, which is closely linked to the former.

In addition to services, the reason for silence can be corrupted system files. Viruses or side effects during the update could damage the libraries responsible for multimedia. To check the integrity of the system, use the built-in utility. Open the command line on behalf of the administrator (find "cmd" in the search, click right-click - "Run on behalf of the administrator").

sfc /scannow

This command will run scanning and automatic recovery of protected system files. The process can take 10-15 minutes. Wait until it is finished and restart the computer. If the utility reports that it found and fixed errors, there is a high probability that the sound will return.

⚠️ Note: Do not interrupt the scanning process sfc /scannow forcefully. This can cause the file system to be damaged and the operating system to be reinstalled.

Hardware malfunctions and connector testing

If the software methods do not help, you will have to move to the "hardware". Computer sound cards (especially those built into the motherboard) are sensitive to voltage surges and static electricity. The front panel connector on the PC body often fails due to constant mechanical impact when connecting headphones.

Try connecting the speakers to the rear connectors of the motherboard. If the sound is gone on the front panel, and the back appeared, then the problem is in the cable running inside the case from the board to the front panel, or in the connector itself. The cable could move away from the contacts on the motherboard (the connector is usually signed as AUDIO or HD_AUDIO).

It is important for USB speakers to check the ports. Connect the device to another USB connector, preferably on the back, directly into the motherboard, bypassing USB hubs and extensions. A lack of power in the port can also cause speakers to be defined but not to produce sound or to make a quiet crackle.

Type of connection	Probable problem	Method of verification	Decision
3.5 mm (Mini-Jack)	Oxidation of contacts, cliff lived	Cable movement, visual inspection	Cable replacement, alcohol cleaning
USB	Power shortage, controller failure	Connecting to another port without a hub	Change the port, update the USB driver
Bluetooth	Interference, desynchronization	Distance check, reconnection	Remove the device, reconnect
HDMI/Optics	Incorrect output format	Checking the settings of TV / Receiver	Change the format in the PC sound settings

If you have a multimeter, you can "ring" the cable. However, given the low cost of most audio cables, it is easier and quicker to buy a new wire or adapter for checking. It is also worth inspecting the connectors for liquid or dust. Compressed air will help blow debris out of the nest depths.

How to clean the 3.5mm connector safely?

Take a cotton swab, lightly moisten it in isopropyl alcohol (not water!) and gently wipe the contacts. Let dry for 5 minutes before connecting. Do not use metal objects to avoid closing contacts.

Specificity of wireless and Bluetooth speakers

Wireless speakers, such as popular models JBL Flip, Sony SRS or Bose SoundLinkThey have their own specifics. Here the radio channel factor and battery charge are added. If the column stops working, check the charge level first. In low charge mode, some models turn off the amplifier, leaving only the indicator to burn.

Problems with pairing are the second most common cause. The device could “remember” the old encryption key or switch to another previously paired device (e.g., a spouse’s phone). Go to your Bluetooth settings on your computer, find your column in the list of devices, select Delete Device, and re-pair the pairing procedure by first putting the column into mode (usually by holding the Bluetooth button).

Interference between Wi-Fi and Bluetooth signals can also cause interruptions or complete disappearance of sound. If the router is close to the Bluetooth speaker or USB adapter, try changing their position. It’s also worth checking if the column is “Aux” mode, which often takes precedence over Bluetooth, is enabled. In this mode, wireless sound transmission is blocked.

Frequent Questions and Answers (FAQ)

Why is there sound in headphones but not in speakers?

This indicates that the sound card and drivers are working properly. The problem is localized in the speakers themselves, the cable connecting them to the PC, or in the connector. Check the cable and connect the speakers to another sound source.

The computer says "Hearphones are connected," even though I haven't connected them, and the speakers are silent.

Most likely, there was a software failure or "sticking" of the contact in the connector. Try to insert and remove the plug several times. If it doesn’t help, reinstall audio drivers or use a third-party utility to reassign connectors (for example, Jack Retasking For Realtek.

Can a virus turn off the sound on your computer?

Yes, some types of malware can block system services or change registry settings, resulting in loss of sound. It is recommended to conduct a full system check with antivirus.

What if the sound is lost after Windows 11 update?

Updates often break the compatibility of older drivers. Go to Device Manager, delete the sound card and click "Update hardware configuration". If it doesn’t help, download the driver from the laptop/board manufacturer’s website, marked as compatible with Windows 11.

Columns make a strong hum or background. Is that normal?

No, a strong hum (50Hz background) indicates poor grounding, poor-quality cable or tips from the power supply. Try turning the speakers, turning off nearby appliances, or using a cable with ferrite rings.
