This tutorial has been explained very well, you can refer to
http://jingyan.baidu.com/article/fb48e8be47d5196e622e143a.htmlWhen we use computers, speakers play a very important role. But occasionally we encounter the problem of no sound from the computer speakers, which is very disturbing. Fortunately, we have some simple and effective solutions to get your computer speakers back to normal again. Below we will answer you step by step.
First, we need to confirm whether the connection between the computer audio and the computer is normal. Please make sure the speaker's power cord is plugged into a power outlet and connected to the computer host. In addition, check whether the audio cable between the speaker and the computer host is connected correctly, usually through a 3.5mm audio jack.
After confirming that the hardware connection is normal, we need to check the volume settings of the operating system. Usually, the volume setting of Windows system is in the lower right corner of the taskbar. You can click the volume icon to adjust the volume. If the volume adjuster is disabled or set to silent mode, please adjust it to an appropriate volume.
Sometimes, the computer may set the audio output device to another device, causing the speaker to have no sound. We can check and set the audio output device through the following steps:
Right-click on the volume icon on the taskbar and select "Sound Settings". Under the Audio tab, select the correct audio output device. If you are using wired speakers, generally select "Speakers (audio input/output device)". Click the "Apply" button to save the settings.If none of the above steps solve the problem, it may be due to an expired or damaged audio driver. We can update the audio driver by following these steps:
Press the Win+R keys to open the run window. Enter "devmgmt.msc" to open the device manager. Expand the "Audio Input and Output" option and find your audio device. Right-click the audio device and select "Update Driver". Follow the prompts to complete the driver update.Finally, if you are using a media player, such as Windows Media Player or VLC Media Player, before playing audio, make sure that its audio settings are not question. Check your media player's volume settings and speaker configuration to make sure they match your system settings.
Through the above steps, you should be able to solve the problem of no sound from the computer stereo. If the problem persists, the audio hardware may be faulty and it is recommended to contact professional technicians for repair.
Thank you for reading this article and hope these solutions are helpful!
If there is a power outage, of course there will be no sound from the computer speakers. Because the data cable connecting the computer speaker to the computer is only for audio transmission, and it requires external power input to turn on and play sound, it will stop working if there is a power outage, which is normal.
1.
Poor contact. The speaker has been used for a long time, causing the internal circuit to age. Poor contact when the speaker is connected to the computer may cause no sound. Solution: First check whether the audio connection is normal. If there is still no sound after making sure it is intact, you can install the driver and see. If it is still not good after installing the driver, it means the audio is broken.
2.
The audio cable is not connected properly, the audio cable is not plugged into the corresponding jack, the volume of the audio is placed at the minimum position, or the speaker is not powered, the computer will fail. The sound is gone. Solution: First turn on the audio switch and turn up the volume. If there is no sound, look at the back of the computer host. The audio output at the back generally has three ports, which are red, green and blue. Red is the microphone, and green is the microphone. It's a speaker, blue is the output, and the speaker wires are also colored. Just plug it into the jack of the same color. After plugging it in, turn up the speaker volume and try to see if there is any sound.
3.
When the audio volume is switched to mute or adjusted too low, sometimes it will happen if the volume is accidentally set to mute or the audio volume knob is adjusted to the minimum volume. No sound
1.
Right-click the volume icon in the desktop menu bar of your desktop computer.

Check whether the sound card driver is abnormal, repair or reinstall the sound card driver.
Extended knowledge:
Computer speakers are divided into conjoined portable computer speakers, which are single cabinets; split computer speakers, which are composed of multiple cabinets. Computer speakers, as the name suggests, are used to connect to computers. Of course, many of them can also be used to connect to other playback devices such as mobile phones. Many Bluetooth speakers, card speakers, etc. can be used as connected portable computer speakers after adding external inputs. This type of speakers is very popular in the market.
Scope of application:
Mainly suitable for Ipod, MP3/MP4, music mobile phones, PSP game consoles, computer products, etc. Depending on the interface, the devices that can be connected are also different.
The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into the space. It is an extremely important part of the sound system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly. It has to directly deal with human hearing, and human hearing is very sensitive. And it has a strong ability to distinguish the timbre of complex sounds. Since the human ear's subjective perception of sound is the most important criterion for evaluating the sound quality of a sound system, it can be considered that the performance of speakers plays a key role in the playback quality of a sound system.
Generally it should be a driver problem. Just download Driver Wizard or Driver Life to install the driver:
1. Open the software and it will automatically detect whether the current driver is faulty and whether it is needed. Repair
2. In the interface, click "Driver" → "Automatic Update" tab, then check the hardware list item whose driver is not installed correctly, and finally click the "Update Now" button to perform the update operation.
