Why does one of the speakers on the computer not work and how to fix the problem?

Loudspeakers are a sophisticated acoustic system that allows the user to provide high-quality sound and contributes to the maximum immersion in the atmosphere of the movie being watched and the music being listened to, and also helps to achieve realism when playing a computer game. Unfortunately, sometimes the technique can crash and stop working. There are many reasons for such a breakdown.

The main thing is to understand how serious the problem you had to face is. Maybe the malfunction is not so dangerous and you can fix it on your own, or maybe it makes sense to contact the support center. To do this, you need to figure out what the malfunctions are.

There are only two types of breakdowns: software failures and hardware failures.

• Crashes in the program. The main reason for such a breakdown is improper processing and transmission of data by the working board. You can deal with such an unpleasant situation on your own without unnecessary material costs.
• Hardware faults. The essence of this problem lies in the fact that one or more elements of the device are simply out of order. To detect a breakdown, it is necessary to make a thorough diagnosis. You cannot cope with this problem alone, so you will have to contact technical support.

Users rarely encounter such an unpleasant situation, when one column is playing and the other is not. Most often, the entire acoustics system fails, and the sound ceases to come from two speakers at once.

Let's consider the most common types of malfunctions.

• External defects of the device and wires that appear in the course of their mechanical damage. If the cord is constantly twisted, it can fray or bend severely, and this will damage it internally.
• Breakage of the speakers themselves or the departure of wires and microcircuits from them. You can see the nominal resistance on the device body. Using a multimeter, you should measure the actual indicators - if they differ from the nominal, then a breakdown is detected and the speaker itself needs to be replaced.
• For wired speakers: incorrect connection of one of the speakers to the USB connector. It is necessary to make sure that the cable marked in green and responsible for audio output is plugged into the correct connector on the computer, marked with the same color. For wireless devices: no Bluetooth pairing or too low battery.
• Penetration of foreign objects into the device such as dust, dirt or even stones. Lack of proper care of speakers and computers often causes interruptions in their work.

These types of faults are most typical for the breakdown of one of the speakers. If there is more serious damage to the system or software, it will not be possible to connect the entire speaker system.

The method of its elimination depends on what type of equipment breakdown belongs to and how complex it is: either an independent solution of the problem, or contacting a service center. If the reason is still unclear, then you can try to correct the situation on your own and take a series of actions that will help check the condition of the equipment as a whole.

• Checking the health of the speakers. If possible, it is recommended to connect them to another computer. The sound that appears will indicate that the speakers are working properly, and the breakdown is related to the computer.

• Inspection of the condition of the device case and the correct connection of the wires. If equipment breakdown is detected, as well as physical damage to the cable, they should be replaced.

• Turning off and on the speakers (if no external signs of breakage were found).

• Ensuring tight connection of wires to the appropriate connectors. Even a slight deviation can lead to loss of sound. If we are talking about a wireless speaker system, then the equipment is searched for on the computer and paired with it.

• Mechanical cleaning of all equipment elements, especially speakers - wiping all components with a dry cloth.

• Sound setting... Sometimes there are computer interruptions and settings are lost, the result of which is minimal sound or even mutes the sound. The following procedure will help you resolve the issue.
  • Login to the "Control Panel".
  • Select "Sound".
  • Select the "Speakers" icon and open their "Properties".
  • If the computer correctly displays the sound equipment, then the name of its manufacturer will appear in the “Controller” cell.
  • The value "Enabled" should be under the block "Device application".
  • Without closing the previous tab, you need to go to the "Levels" section and in the "Dynamics" block bring the indicators to 90%.
  • Open the "Advanced" tab. Run the "Test", during which a short melody should sound.

• Driver setting. To ensure that the driver works properly, the following procedure.
  • "Control Panel".
  • "Device Manager".
  • Double-click the left mouse button to select "Sound, game and video devices".
  • In the menu that appears, right-click on the "Update drivers" setting.
  • In the dialog box that opens, click on "Search automatically for updated drivers".

• Scanning your computer for viruses. Sometimes viruses can knock your computer settings down and your speakers stop working. If the antivirus is installed, you need to run a full scan of your computer for threats, if not, install it.

• Computer reboot... It is often this simple manipulation that helps bring the sound back.
