This article will explain in detail how to solve the problem that there is no sound in the computer, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

There's no sound on the computer? This topic has been heard in my ears countless times, dealing with the fault is also from the previous groping to solve to now can quickly find the cause. But for novice friends, they may not know where to start, and they may not be able to give a countermeasure as to why the computer has no sound.

In fact, there are only two reasons for the lack of sound in the computer, namely, computer hardware problems and software problems. The hardware problem is mainly the sound card is broken, or the output sound interface is damaged and so on. Generally, the hardware damage of the sound card is very few. The author has to encounter the lack of sound caused by the hardware problem, and the software problem is the more common cause of the computer to have no sound. So how to determine whether it is a hardware problem or a software problem / let's explain it in detail.

Generally speaking, we usually deal with computer failures first by software before hardware. If your computer has no sound, please try the following solution, which can be solved generally.

One: if the computer has no sound, please first check whether there is a sound control icon in the lower right foot taskbar of the computer desktop, as shown below:

Computer desktop sound icon

As in the picture above, if there is this icon to show that there is no problem for the sound card to be installed on the computer, and then click the sound control icon with the left mouse button, the sound volume adjustment switch control window will appear to see if the volume is adjusted to a minimum. Is it checked to mute? in the past, many novice friends used to help many novice friends to deal with no sound on the computer when they either set the sound to the lowest level or checked mute. As a result, there is no sound on the computer, which is a low-level mistake often made by novice friends.

If the volume control icon above cannot be found on the computer desktop, it may be a driver problem. If you look at the driver problem below, you will know how to reject it, and some of it is not displayed. The way to make it show is as follows:

If there is no "small speaker" on the right side of the taskbar, enter the start-Settings-Control Panel-Sound and Audio device command and open the Sound and Audio device Properties dialog box, as shown below:

As in the picture above, click on the √ to make sure that there will be a sound icon in the lower right foot taskbar of the desktop, and then check whether the volume is adjusted and muted. After recuperation, the computer generally has a sound.

You can also click the sounds tab in this dialog box, then click one of the program events (such as a program error) in the Program events bar, select a sound category, and see if the Preview button on the right is black. If it is black, the sound card is normal and the failure may be due to the low volume of the system, or muted, or speaker failure.

Other reasons: if there is no sound card option in the device Manager window and the sound card is an integrated sound card, then restart the computer and enter the BIOS program. Then check that the peripheral option in BIOS is set to "Disabled", and if so, change it to "Enable". If this setting I "Enable", it may be the motherboard sound card circuit damage, repair the sound card circuit. We'll just have to take it for repair.

Second: if there is no sound in the computer, please first check whether there is something wrong with your speaker or earphone, whether the speaker or earphone audio cable is well connected to the computer, and whether the port is plugged in correctly.

In the past, it was found that when a friend used a speaker or earphone, there was no sound due to connecting the audio cable to the computer, which is also a very low-level mistake. How can there be sound if there is no signal connected to the speaker? Some are directly connected to the microphone interface of the computer, and they all feel amused when they read it. There is an audio interface and a microphone in the computer interface. Everyone must look at it for themselves. There is an icon on it. Obviously, if a complete rookie does not understand, you can ask the people around you and read the instruction manual. If there is no sound in the computer before, you can take a good one to check whether the earphone or speaker is damaged.

Also note that most desktop computers have two pairs of audio interfaces, distributed in front and back of the chassis, so try the back Jack if the front interface is useless. Because some computer installers may forget to connect the Jack signal cable in front of the mainframe to the motherboard. At this point, the author has encountered a lot of this kind of situation.

Three: check whether the computer sound card driver is installed properly.

In the past, it is often encountered that the computer has no sound after the computer system is reinstalled, which is mostly caused by the incompatibility of the computer sound card driver. The solution is to find the corresponding driver for the computer sound card to install. How to find out if the installation of the computer sound card driver is abnormal? We can access my computer-right-click-Select-Properties-- hardware-- device Manager as shown below:

My computer properties

Click device Manager to enter the following computer hardware drivers to view, as shown below.

Interface for normal sound card driver installation

Such as the above picture is a normal screenshot of the sound card installation driver, the sound card driver installation screenshot is like this, there is a yellow exclamation point on the sound card device! As follows:

The sound card driver is abnormal and exclamation mark is displayed.

If there is an exclamation point in the sound card driver, it means that the hardware driver in the current system does not meet the computer driver, and the solution can be to change the system. Of course, it is not necessary to find the computer sound card model. Baidu can find the driver installation directly. How to check the sound card hardware model of your computer? There are many methods. Here are a few simple ones:

Method 1: start-- run-- enter: dxdiag command-- make sure you can open the Direct X hardware diagnostic tool, and then select the sound to see the sound card model. As shown below:

Direct X Diagnostic tool

Check the sound card model can also be tested with Master Lu software.

Know the sound card model, directly in Baidu search input sound card model driver download, generally can be found, download can be installed, the installation method here is briefly introduced.

Click the yellow exclamation point shown in the image above, click to reinstall the driver-Select install from the list-Select the path to download the sound card-- and then confirm all the way to complete the installation. Novice friends suggest using the following method to download a "driver wizard" software, which is very convenient to install directly in the software. Driver wizard download address: https://www.yisu.com/softs/41724.html (most sound cards are integrated). There are many such software, such as 360 butler and other software, the operation is very simple and suitable for novice friends to use. There are no more introductions here.

Other reasons (usually rare)

If the sound card is not an integrated sound card, then open the chassis and check that the sound card is installed. If not installed, reinstall, boot test; if the sound card has been installed, then remove the sound card, and then clean the motherboard sound card slot and sound card above the dust (especially to check whether the golden finger has mildew spots, etc.), after cleaning, and then re-installed, the general fault can remove the computer without sound. At present, most of the computers we use are integrated with sound cards.

There are also reasons for damage to the computer sound card, damage to the computer audio output interface, and so on, which are generally rare. If you encounter it, you can only take it to a professional computer maintenance shop for inspection and repair. the above is the computer Pepsi network editor based on his many years of experience for everyone to write to solve the common problems and solutions of computer no sound, because the preparation time is in a hurry, if there is any impropriety, welcome to supplement and comment.

There is no voice on the computer how to share here, I hope the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
