What if the computer audio has no sound?
There is no sound in the computer audio - hardware reasons:
1. Poor contact: The internal circuit is aging due to the long-term use of the audio. If there is poor contact when the audio is connected to the computer, there may be no sound.
Solution: First check if the audio connection is normal. Make sure that there is no sound after the installation is complete. If the driver is not installed well, it means the sound is broken.
2, the audio cable is not connected: the audio cable is not plugged into the corresponding jack, the volume of the audio is placed in the minimum position or the speaker is not powered, there will be no sound of the computer.
Solution: first turn on the audio switch, turn the volume up. If there is no sound, look at the back of the mainframe. The audio output on the back usually has three ports, red, green and blue. Red is the microphone, green. It is audio, blue is output, and the audio cable is also colored. It can be inserted into the jack of the same color. After plugging in, turn on the sound volume and try to see if there is any sound.
3, the audio volume is switched to mute or too small: sometimes you will accidentally set the volume to mute or the volume knob on the minimum volume, there will be no sound.
Solution: Click the speaker icon in the lower right corner of the system to confirm whether the volume is turned on and adjust the sound to the appropriate size. If the "small speaker" icon in the lower right corner is gone, go to the "Control Panel" and double-click the "Sound and Audio Device" item. In the pop-up "Sound and Audio Device Properties" window, select the "Volume" page and then Adjust the volume adjustment slider to the appropriate position and check the “Put the volume adjustment icon into the taskbar†to confirm and exit.
4, computer sound card damage: the general computer does not have much sound and software, but does not rule out the damage of the sound card itself.
Solution: If the sound card hardware is damaged, you can buy a separate sound card to plug it in.
Computer audio has no sound - software reasons:
1. The sound card driver is abnormal: the sound card driver is disabled, the sound card driver is damaged, or the device driver that is not supported is installed, which is the main cause of the computer sound.
Solution: Right click on the "My Computer" icon, select "Properties" - "Hardware" - "Device Manager", open "Sound, Video and Game Controller", if the yellow "?" appears in front, the sound card is The driver is not installed, just reinstall the sound card driver to solve the problem. If the "Cannot find AC chip" prompt appears when installing the sound card driver, the sound card driver may be deleted by mistake or the computer may be poisoned or internal software conflicts. In this case, you can only reinstall the system and drivers.
2, the virus in the computer : If the computer is a virus, it damages the files related to audio processing, especially the system components related to Dsound.
Solution: Use anti-virus software to check whether the computer has a virus. If there is a virus, it will be quickly detected and killed. If the virus is too stubborn to be completely removed, you can restore or reinstall the system with one click.
3. The sound component is not installed: usually the speaker has no sound and the small speaker icon is not visible in the lower right corner.
