Hello friends:

Suddenly there is no sound, it may be that the socket of the headphones or speakers is not plugged in tightly, loose, Jianyi plugs it in again, if you rule out this reason, which is caused by the following reasons: There are many reasons why the computer has no sound, and there are different solutions for different situations, and the main reasons are divided into two major reasons: hardware and software:

1) The hardware aspect is mainly: whether the headphone jack connected to the motherboard is damaged, whether the headphones are damaged, whether the audio is damaged, and even whether the motherboard audio chip is damaged (of course, this reason is very small), the main reason is still from the software.

2) The main reasons for software are: the following points and solutions.

1. There is a sound when the computer is turned on, and there is no sound after that:

The main phenomenon is: The audio icon is normal, and when it is opened, it beats but you can't hear the sound]: Check the security software of the computer, such as Tencent Butler, etc. You can disable it first, set it to not start automatically, and then restart the computer to give it a try.

Second, after the computer was turned on, there was no sound:

1 First of all, you need to see what the audio icon in the lower right corner looks like: it generally has 2 states, one is a small cross state, and the other is a red forbidden state.

2.If it's a small cross, the state indicates a few problems:

1) The audio driver is not installed.

2) The audio service was stopped and banned.

3) In the sound options, the speaker is disabled.

3.Solution:

The third phenomenon appears, which may have been solved in the previous 2.

The first phenomenon is not installed, if there is an installation disk, you can click on the corresponding sound driver to install, and restart the computer. If you don't have an installation disk, you can drive the wizard and then install the missing driver.

How to deal with the second phenomenon: the audio service is stopped and banned: the window icon in the lower left corner is required.
