I believe that for many people, finding no sound when using a computer is a very frustrating news. So how to restore the computer if there is no sound? What is the reason for the lack of sound in the computer? Now, let the editor of Superman software answer them one by one for everyone, I hope it will be helpful to everyone.
How to restore computer without sound?
Method 1: Check the sound control icon
If the computer has no sound, please first check whether there is a sound control icon in the taskbar on the lower right foot of the computer desktop.
. 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, the sound volume adjustment switch control window will appear, check whether the volume is adjusted to the lowest level, and whether it is checked. Mute, when I used to help many novice friends to deal with the lack of sound from the computer, many of them either turned the sound to the lowest level, or checked mute, resulting in no sound from the computer. This is a low-level mistake that novice friends often make.
If the volume control icon above cannot be found on the computer desktop, it may be a driver problem. See the following to know how to solve the driver problem. Some of them are not displayed. The method to make it displayed is as follows:
If there is no "Speaker" on the right side of the taskbar, go to Start - Settings - "Control Panel - Sound and Audio Devices" command to open the "Sound and Audio Device Properties" dialog box.
After ticking √, click OK. There will be a sound icon in the taskbar at the lower right foot of the desktop. Then check whether the volume is adjusted and whether the mute is clicked. After the computer is closed, there is usually a sound.
You can also click the "Sound" tab in this dialog box, and then click one of the program events (such as a program error) in the "Program Events" column, select a sound type, and then see if the "Preview" button on the right is is black. If it is black, the sound card is normal, and the cause of the failure 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 the BIOS is set to "Disabled", if so, change it to "Enable". If this item is set to "Enable", it may be that the sound card circuit of the motherboard is damaged, and the sound card circuit can be repaired. Just take it for repairs.
Method 2: Check if there is a problem with the hardware
If there is no sound from the computer, please first check whether there is a problem with your speakers or Earmics, whether the speakers or Earmics audio cables are well connected to the computer, and whether the interfaces are plugged in correctly.
In the past, I found that there was no sound when a friend used a speaker or earmuff because the audio cable was connected 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 computer's microphone. The interface is gone, and I feel amused when I 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. The instructions are better than anything else. If the computer used to have sound and now there is no sound, check whether the headset or speakers are damaged. You can try a good one.
It should also be noted that, in general, desktop computers will have 2 pairs of audio interfaces, which are distributed in the front and rear of the chassis, so if the front interface is useless, you can try the rear socket. Because some computer installers may forget to connect the signal line of the socket on the front of the host to the motherboard. I have encountered this situation a lot.
