Win8 laptop has no sound solution

There is no sound when playing a web video on a Win8 laptop. There is no sound when opening a local video file. It means that there is no sound in a program, but the sound of the whole laptop in Win8 has a problem. Let me introduce it. The solution to this problem.

First, the sound card is not installed

1, right click "My computer" - "---" & ldquo; management & rdquo;.

2. Click on “Device Manager" on the left.

3. Check if there is a yellow exclamation mark in this place. If there is, it will prove that the sound card is not installed. If not, check other reasons. If the sound card is not installed, you need Baidu to scan your own graphics card driver, then download and install it.

Second, manually turn off the sound

1, manually turn off the sound, this is also a problem encountered by many users.

Third, the machine settings are not right

1, many friends set the speaker, the settings are wrong, this is also the reason for no sound. If you plug the device into the back of the chassis, how do you set it up? Slide the mouse to the lower right corner and click “Set”---“Control Panel”

2. Set it in the "sound"

The above is the solution for the Win8 laptop without sound. If there is no problem with the audio equipment, Win8 has no sound, which is generally the above three reasons. Of course, Win8.1 has no sound, you can refer to: Win8.1 system has no sound repair measures to deal with.
