Many people have been to the computer and suddenly there is no sound? How to solve the problem that the computer has no sound? The following is my simple analysis. I hope it can help you!
Generally, we deal with computer faults first with software and then hardware. If your computer has no sound, please try the following solutions, which can generally be solved.
Method 1: check the sound control icon
If the computer has no sound, please check whether there is a sound control icon in the taskbar at the lower right foot of the computer desktop, as shown in the following figure:
As shown in the figure above, if there is this icon, it means that there is no problem with the sound card installed on the computer. Then click the sound control icon with the left mouse button, and the sound volume adjustment switch control window will appear to check whether the volume is adjusted to the lowest and whether mute is checked. In the past, when many novice friends were dealing with no sound on the computer, they either adjusted the sound to the lowest or checked mute, It leads to no sound on the computer, which is a low-level mistake that novice friends often make.
If you can't find the volume control icon on the computer desktop, it may be a driver problem. For the driver problem, see the following to know how to resolve it. Some don't display it. The methods to display it are as follows:
If there is no "small horn" on the right side of the taskbar, enter the command of start - Settings - control panel - sound and audio devices, and open the dialog box of "sound and audio device properties", as shown below:
Check if there is sound on the desktop and turn down the √ icon as shown in the figure above, and then check whether there is sound in the task bar. If there is sound on the desktop, it will be checked if there is sound in the task bar.
You can also click the "sound" tab in this dialog box, then click one of the program events (such as program error) in the "program events" column, select a sound type, and then see whether the "Preview" button on the right is black. If it is black, the sound card is normal. The fault may be that the system volume is too low, or the mute is set, or the speaker is faulty.
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 whether the peripheral device option in BIOS is set to "disabled". If so, change it to "enable". If I set "enable" for this item, the sound card circuit of the mainboard may be damaged. Repair the sound card circuit. It can only be repaired.
Method 2: check whether there is a problem with the hardware
There is no sound in the computer. Please check whether there is a problem with your speaker or earpiece, whether the audio cable of the speaker or earpiece is well connected with the computer, and whether the interface is plugged in correctly.
In the past, I found that there was no sound when a friend used a speaker or earpiece because he connected the audio cable to the computer. This is also a very low-level error. How can there be sound when there is no signal connected to the speaker?? Some are directly connected to the microphone interface of the computer. They all feel funny when they read it. One of the computer interfaces is an audio interface and the other is a microphone. You must read it yourself. There are icons on it. Obviously, if a rookie doesn't understand it at all, you can ask the people around you and read the instructions. If there was a sound in the computer before, now there is no sound. Check whether the ear step or the speaker is damaged. You can try a good one.
It should also be noted that the general desktop computer will have two pairs of audio interfaces, distributed in the front and back of the chassis, so if the front interface is useless, you can try the back socket. Because some computer installers may forget to connect the socket signal line in front of the host to the motherboard. The author has also encountered many such situations.
Method 3: check whether the computer sound card driver is installed normally
In the past, we often encountered the situation that the computer has no sound after the computer system is reinstalled. Most of this situation is caused by the failure or incompatibility of the computer sound card driver. The solution is to find the driver corresponding to the computer sound card and install it. How to find out if the computer sound card driver is not installed properly? We can enter my computer - right click - Select - properties - hardware - Device Manager, as shown in the figure below:
Click device manager to enter the following computer hardware driver to view, as shown in the following figure.
As shown in the figure above, the screenshot of sound card driver installation is normal. The screenshot of sound card driver installation problem is like this. There is a yellow exclamation mark on the sound card device! As follows:
If there is an exclamation mark in the sound card driver, it indicates that the hardware driver in the current system does not meet the computer driver. The solution can be to change the system again. Of course, it is not necessary. Just find the computer sound card model and directly Baidu to find the driver installation. How to check the sound card hardware model of your computer? There are many methods. Here are some simple methods:
Method A. start - run - enter: dxdiag command - OK, you can open the direct x hardware diagnostic tool, and then select - sound to see the sound card model. As shown below:
Method B. click the yellow exclamation mark shown in the figure above, click reinstall 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. It is very convenient to operate and install directly in the software. There are many such software, such as 360 housekeeper and other software.
