A laptop is a very reliable and convenient device for people who want to have a mobile workstation at hand. But what to do if the sound on the laptop is gone? This may indicate both hardware problems and changes in the operating system of the device. Troubleshooting some problems is quite simple. And to eliminate others, to restore sound on a laptop, you will need certain skills and knowledge.
First — reboot
If the sound suddenly disappeared in the laptop, when you start any application, you should try to completely reboot the system.
Advice! In this case, it is recommended only to save your work data without closing any programs.
If the sound suddenly stops working, you need:
- press Start-Shutdown;
- select Reboot;
- when prompted to force close applications, confirm your choice.
By performing actions in this way, you can prevent the application of the settings that were initialized by the muted application. The fact that the problem has been fixed will be indicated by audio greeting when the system boots.
Random button presses
The laptop is quite compact. Keyboard buttons are often pressed accidentally. Therefore, in order to restore sound on a laptop, you should first try the desired functional combination.
Advice! You can find out what exactly you need to press from the instructions for your model.
But you can find the necessary buttons when the sound suddenly disappeared without studying the documentation. It is worth taking a close look at the keyboard. A key, except for the main symbol, which shows a crossed-out speaker, when pressed simultaneously with Fn, turns off the sound. Using this combination, it is easy to fix the situation when your favorite track or movie is not playing.
Similarly, if there is no sound, you can try turn up the volume. This is also done by functional keyboard shortcuts. The necessary buttons are indicated by symbols with a speaker, a plus and a minus. On different laptop models, their location may vary. For example, on HP, Acer products, the volume is changed using the Fn + arrow keys.
Software mute volume
If there is no sound on the laptop, it is worth looking at the speaker icon in the taskbar next to the clock. If it is crossed out, then the audio output is programmatically disabled. You can adjust the settings and return the sound as follows:
- in Windows 7, Windows 8, left-click (LMB) on the icon in the taskbar, move the slider to the maximum in the opened regulator;
- in Windows 10, the procedure is similar, the slider is a horizontal bar, move the slider to the right.
The reason why there is no sound on the laptop may be programmatically disable output for individual applications or system. To get to the desired settings, you should click on the speaker icon near the clock with the right mouse button (RMB). In Windows 7, Windows 10 in the drop-down menu there is an item Open volume mixer. The mixer window lists all applications that are currently accessing the audio card. By changing the positions of the sliders, you can solve the problem when there is no sound only when the video or audio player is running.
Wrong playback device
Sound may not work when the wrong playback device is used on the system. This problem is present on models with HDMI output or sophisticated audio cards.. If the sound does not turn on, you should:
- right-click on the speaker icon in Windows 7, Windows 10;
- select the Playback devices section from the drop-down menu.
The laptop only outputs sound through built-in speakers. This device is called Speakers/Headphones. In the window that opens after selecting the Playback devices item, you need to check:
- are the speakers turned off, is there a cross on the device icon;
- whether the output to the speakers is carried out, whether there is an icon in the form of a green check mark on it.
The fact that everything is in order is indicated by the level indicator next to the device name. If there is no sound, it will be grayed out.
Advice! An easy way to identify the cause of the problem and restore the speakers to work is to use the system wizard. It detects most of the incorrect settings and offers to change them automatically.
If the sound does not turn on, just:
- turn off any speakers, headphones from the laptop;
- right-click on the speaker icon;
- Click on Troubleshoot from the drop-down menu.
All that is required from the user is to wait for the wizard to finish. When there is no sound on a laptop due to a change in system settings, the troubleshooter will detect and fix them on its own.
Unfortunately, problems with sound card drivers can occur through no fault of the user. This happens when updating the system, installing various software. To evaluate driver statuswould need:
- go to Start-Control Panel-System, click the Device Manager button on the active tab;
- right-click on Computer, select management, section Manager in the left column;
- press Win + R and type the command devmgmt.msc.
Using any of these methods, you can call up a list of devices installed in the system. Audio drivers are located in the Sound Devices section. In case of problems, the block will be deployed immediately. When the name of an audio device is red cross iconright-click on it and select Enable.
Yellow triangle icon means that the drivers are not working properly. First of all, it is worth trying to roll back the installation and return to a working version. To do this, you need:
- click on the name of the RMB device;
- select Properties from the menu;
- go to the Driver tab.
There is a rollback button here. After clicking it, the system will try to remove the latest installed driver version. The laptop should be restarted.
Driver Pack Update
If there is no sound on the laptop, and rolling back the driver version does not help, you need to update all sound software modules. This will require:
- download a complete set of drivers from the laptop manufacturer’s website;
- remove all audio devices from the system using the task manager;
- install downloaded drivers;
- restart laptop.
If the audio card not physically damagedwhich happens due to static impact on Lenovo models, drivers from the manufacturer will definitely allow you to restore sound on a laptop.
For each laptop, BIOS settings are stored on battery powered chip. The latter is not eternal, and after many years of use it may turn out that when you turn it on, there is no sound on the laptop. This means that you need to check the BIOS.
Enabling and disabling the sound card on laptops can be done in different sections. For ASUS products, this is Advanced, in some Lenovo, HP — Integrated Peripherals. The audio card itself can be referred to as High Definition Audio, Onboard Audio Chip, or a line with the manufacturer’s name ending in Codec (for example, Azalia Codec). The value of the option must be set to Enabledto bring back sound on the laptop.
The 3.5 mm headphone minijack connector, which is found in almost all laptops, has a service contact. It tells the audio card to turn off the speakers to play sound only on the headphones. Over time, the service contact can become deformed and constantly transmit information to the system that the headphones are connected.
The problem does not appear unexpectedly. The sound begins to disappear when the plug is moved, plays unevenly in the headphones, there is only one loudspeaker. If this situation develops, the speakers may turn off precisely due to connector problems. As a result, the sound does not work in any application.
Advice! If you do not have enough skills to clean and repair the nest yourself, you should contact the service.
System service failure
The most rare problem when the sound does not turn on is the failure of the Windows Audio system service. This usually indicates driver problems. You can manually enable the Windows Audio service by going to Computer Management, Services section. But doing it all the time doesn’t make sense. Sooner or later, the problem will develop into a situation with a complete lack of sound. Therefore, it is worth restarting the laptop and proceeding with the methods described in this article.
