The speaker of the laptop suddenly stopped ringing, there is no quality problem, solve it

There is no sound on the computer, such as no sound when the computer is turned on, and the small speaker in the taskbar is missing. I've come across it three times on my computer. After repeated exploration, I finally found several solutions.

Now I dedicate it for the reference of netizens.

First of all, the computer is silent, but sometimes the problem is more complicated, involving both hardware and software problems. It is also common for the sound card to not sound and the small speaker to disappear due to sudden crashes. Therefore, it is necessary to find out the cause first, see if it is a software failure or a hardware failure, and then prescribe the right medicine for the problem and solve it properly.

We must not mess around for unknown reasons, because if we don't do it, the system will be paralyzed, and the trouble will be big.

1. Check whether the sound card, cable, speaker and other devices are connected normally. If you have a virus, you should run antivirus software for full antivirus.

2. Open the control panel--- Add new hardware--- Next, after the search is completed, click "No, I haven't added this hardware", click Next. In the dialog box that appears, check Click Done, shut down the computer, restart to add new hardware. Note that this refers to shutting down and then starting, not restarting.

In general, the problem can be resolved after rebooting.

3. Right-click "My Computer" --Properties--Hardware"--Device Manager", and open "Sound, ** and Game Controller" for any problems, that is, see if there is a yellow one in front? If so, uninstall it, then put it into the CD drive and reinstall the drivers for this device.

4. If the "Device Manager" - Sound, ** and Game Controller" is no sound card hardware, then you have to find your sound card, including the integrated sound card, the model must be accurate, after confirming that the sound card is found, then put it into the system drive disk, install the sound card driver.

5. When there is sound but you don't see the small speaker, don't panic, just open the control panel --- the sound and the --- volume of the device, and put the check mark before "put the volume icon into the taskbar", and there will be a small speaker in the taskbar after restarting.

6. When there is no sound and no speaker, open the control panel--- add and remove programs--- add and delete windows components, and put in.

7. If the above steps do not solve the problem, then you have to reinstall the system and drivers, and all problems will be solved, but the premise is that all kinds of hardware are in good condition and there is no conflict in the software.

8. When the sound card driver is installed, the "AC chip cannot be found" prompt appears, it may be computer poisoning, or the sound card is plug and play loose, resulting in poor contact, or it may be due to illegal operation and mistakenly deleted the sound card driver, or internal software conflicts. This is a step-by-step approach for different causes.

9. Simply ignore it, you can gently pat the shell of the computer body, the laptop can cover the lid when the force is slightly larger than usual, so that some loose parts are restored, and after shutting down, wait for a period of time before restarting, sometimes the sound problem will be restored. You might as well give it a try.
