The lack of sound in laptops is a problem that people often encounter when using laptops. Many people are not able to play games and watch movies very well. So why is there no sound in laptops? What if the laptop doesn't sound? The following decoration home decoration network Xiaobian will give you detailed answers for your reference.  What if the laptop doesn't sound? 1. If there is no sound in the computer, please check if there is a sound control icon in the task bar on the bottom right of the desktop. If there is this icon, it means there is no problem installing the sound card on the computer, then click the sound control icon with the left mouse button, the sound volume adjustment switch control window will appear, check whether the volume is adjusted to the minimum, is it checked? Mute, in the past, when many novice friends dealt with the computer without sound, many of them either adjusted the sound to the lowest level, or checked the mute, which caused the computer to have no sound. This is a low-level mistake that novice friends often make. If the above volume control icon is not found on the desktop of the computer, it may be a driver problem. If you look at the driver problem, you will know how to reject it. Some of them are not displayed. The way to display it is as follows: If there is no small speaker on the right side of the taskbar. Go to Start - Settings - Control Panel - Sounds and Audio Devices command to open the Sound and Audio Device Properties dialog. After hitting √, make sure there is a sound icon in the task bar on the lower right side of the desktop. Check again, whether the volume is adjusted and whether it is muted. After the break, the computer usually has a sound. 2. If there is no sound in the computer, please check if there is any problem with your speaker or ear, whether the speaker or ear audio cable is well connected with the computer, and the interface is plugged in. When using a speaker or an ear, it was a low-level error because the audio cable was connected to the computer. There was no signal to connect to the speaker and how to make a sound. Some are directly connected to the microphone interface of the computer. The computer interface has an audio interface and a microphone. It should also be noted that a typical desktop computer will have two pairs of audio interfaces distributed in front of and behind the chassis, so if the front interface is useless, try the rear socket. Because some computer installers may forget to connect the socket signal line on the front of the host to the motherboard. I have encountered many of these situations at this point. 3. Check if the computer sound card driver is installed normally. Some users often encounter no sound after reinstalling the computer system. This situation is mostly caused by the computer's sound card driver not installed or the driver is not compatible. Find the corresponding sound card driver installation (it is recommended to download a "drive wizard" to install). The method is as follows: Open the "My Computer" button in turn - select to - "Properties" - "Hardware" - "Device Manager", we click on the "Device Manager" to enter the computer hardware driver to view. There is a yellow exclamation mark on the sound card driver installation problem. If there is a yellow exclamation point in the sound card driver, it means that the sound driver in the current system is not properly installed or the sound card driver is not compatible. Of course, we can re-install the system again, but personally feel that it is not necessary, we just need to find the corresponding computer sound card model, and then directly on Baidu to find the corresponding sound card driver, and then download to the local installation. 4. If the sound card is not an integrated sound card, we only need to open the chassis to check if the sound card hardware is loose. If it is loose, then we can plug it in. 5, if the sound card hardware is not loose, intact installation, then we can try to pull out the sound card, and then use the brush to clean the dust inside the motherboard sound card slot (U start reminder: focus on check whether the golden finger has mildew), clean up After cleaning, plug the sound card in, remember to plug it in, of course, don't use it, don't break the sound card. 6, other causes of failure may be the computer sound card is broken or the computer audio output jack is damaged, but this situation is rare, if you are unfortunately met, then only recommend that you go to the computer repair shop to repair Or replaced it.
