How to fix a laptop with no sound
In the process of using our laptops, it is inevitable that we will encounter a laptop suddenly no sound, which will undoubtedly bring a lot of trouble to daily life. This article will provide a comprehensive set of solutions to help restore the computer's normal audio output.
1. Check the volume settings
1) confirm the system volume
First, check whether the volume of the laptop is muted or minimized. Find the volume icon in the lower right corner of the taskbar to confirm that the volume is turned on and adjusted to the appropriate level.
2) Check the application volume
Sometimes, individual applications may be individually muted even if the system volume is normal. Check the volume control within the application when playing media.
2. Software level checking
1) Update the sound card driver
Outdated or corrupted sound card drivers are a common cause of no sound. In order to help you quickly determine whether there is an abnormal sound card driver, we recommend that you can directly through Driver Sentry to scan and update the old version of the driver, including the sound card driver.
After the update is complete, restart your computer to make it take effect.
2) Check the audio settings and device manager
In "Control Panel", go to "Sound" settings, make sure the default playback device is correctly set to the device you want to output sound.
Open "Device Manager", check whether there is a device with a yellow exclamation mark under the category of "Sound, Video and Game Controllers", which means that there is a problem with the driver and it needs to be updated or reinstalled.
3) reset audio services
Sometimes, the Windows audio service is not running can also cause no sound.
Press the "Win + R" key combination to open the Run dialog, type "services.msc", and then press Enter to open the Services.
Find the "Windows Audio" service and make sure it is in the "Running" state, if not, right click and select "Start".
3. Hardware check
1) external speakers or headphones check
If you are using external speakers or headphones, please try to unplug these devices first, and use the built-in notebook speakers directly to test. This helps to determine whether the problem is in the computer or peripherals.
2) Built-in speaker check
Make sure the speakers are not physically clogged, such as dust or foreign objects that are blocking the sound from coming out. Blow gently or use a soft cloth to clean the speaker grille.
3) Interface and wiring check
If there is no sound from headphones or speakers connected through the headphone jack, check if there is any damage to the headphone jack, and try plugging in other devices to test if the interface is working properly.
These troubleshooting steps can help you quickly fix problems and restore sound to your computer. Regularly updating your sound card drivers and maintaining your computer system can prevent future problems.
